Product Description of High-performance pipeline ball valve-reduced bore:
High-performance pipeline ball valve is Raymond(RMD)hightech products,as switch control equipment,it is mainly used in natural gas,oil,gas,liquefied natural gas pipeline transmission system and other industries,its anti-sulfur products containing hydrogen sulphide,impurities and high corrosion are suitable for the long-distance natural gas pipeline.
Design Features of High-performance pipeline ball valve-reduced bore:
Body of high-performance pipeline ball valve is forged structure.The connection type for body and vice-body can be BB(bolted connection)and WB(welded connection).The WB(welded connection)and the LWB(Fully-welded extended stem)structure isadopted for buried ball valves,as shown below.
High performance pipeline ball valve series has the feature of strength, high perfect sealing, maintenance-free, long life and so on. The production of this series ball valve adopts the international advanced ball valve design and manufacturing technology, selects high-quality materials in accordance with the standard selection of materials and combines with advanced materials forming forging technology. At the same time, with the years of ball valve design and manufacturing experience, the use of advanced processing and manufacturing equipment and production and processing technology, through the first-class inspection and testing equipment and instruments, perfect quality assurance management system and excellence in the production of high-performance philosophy can ensure the quality of valves. This series of valve has the performance of a high strength, defect-free forging body, excellent sealing performance, even at maximum pressure difference(full pressure),it will still be able to ensure that seal without leakage, after frequent switching action to realize a safe usage in the transportation of oil, natural gas, coal gas, and other special medium transportation pipeline.
The special structure of valve seat seal of High-performance pipeline ball valve-reduced bore:
Floating structure means seat reciprocally can move along channel direction,so as to guarantee the ball and seat are tightly sealed.
(Ⅰ)Valve seat structure suitable for different occasions and sealing requirements
Valve seat can be designed as a standard single-piston effect and specific dual piston effect,Figure1 shows single-piston effect-inletside seal;Figure2 shows Dual Piston effect-outlet-side seal;Figure3 shows special dual piston effect sealing structure
(Ⅱ)Multi-level structure of the valve seat seal
As shown in Figure4,there are two elastic O-ring in the valve seat ring-ring A and ring B.Sealing ring A spring-loaded through the valve seat so that the sealing surface of sealing ring A tightly fit with ball surface to form an initial seal.When there is pressure in the system medium,the piston force
produced by the piston force produced by the piston effect of size difference makes elastic deformation of the ring A Ershi sealing surface and ball more closely fit the surface to form a re-sealing;meanwhile,due to ring A in the medium resulted in elastic deformation under pressure so that the sealing ring B is also closely fit the surface of ball for the formation of the second stage seal.When the system medium pressure increasing,it will have an enormous pressure in the valve seat ring A and ring B,so that the two seals have a greater elastic deformation,and then the metal valve seat ring surface and the ball surface sealing together to form a third level of metal to metal seal.
(Ⅲ)The assisted valve seat sealing equipment
Based on the actual service condition,medium requirement,sealing requirement,etc.,the assisted valve sealing equipment will be considered to be necessary or not.The assisted valve sealing equipment is a one-way valve installed outside of valve body that can prevent medium leakage and can inject sealing grease into valve body by external force.When the assisted valve seat sealing equipment is required,valve seat ring shall be design and processed with injection grove and hole to connect the assisted valve seat sealing equipments.Such equipment can prevent the medium by the sealing of injection of rease.Refer to Figure5 for reference.
Multi-level structure of stem sealing
Figure6 shows the stem multi-level sealing by adopting"O"ring,flexible graphite and grease injection;"O"ring achieves the first level stem sealing;Replaceable flexible graphite realizes the second level sealing by the compression of packing sleeve and packing flange;And the third evel sealing is realized by installing assisted sealing injection valve to the packing box,and by designing with the injection groove and hole to connect with the stem injection valve,which can inject grease.
Unique and safe seat structures of High-performance pipeline ball valve-reduced bore:
Ball valve fireproof design is implementation of the API607,API6FA standards.According to service conditions and user requirements,ball valve can be designed as a fireproof structure.
(Ⅰ)Fireproof structure of seat
As shown in figure7,there is composite fireproof ring,which are combined with graphite and stainless steel wire in the seat.Once the soft ring is burnt out in case of a fire,the fireproof ring and seat ring will form a piston structure through the spring to load the valve body.That will push and closely contact the metal seal surface of the seat ring to the body surface,So as to prevent a lot of medium from leaking from the burnt place of the seat ring,and prevent the fire from expending.
(Ⅱ)Fireproof structure(body and bonnet)
The seal gasket for bolt connecting valve body and valve bonnet,are used fireproof stainless steel wire and flexible graphite gaskets.Gasket compression load through the bolts and ultimately,ensure the valve body and valve cover between the metal to metal contact,so that the valve can with stand more high load,but also improve the fire safety of the valve.But for the full welded ball valve,the valve body and cover is welded structure,that fundamentally eliminate the possibillity of leakage of the valve housing.Even in the case of fire damage,there will be no leak.
(Ⅲ)Fireproof structure(body/packing and stem)
The body and packing connection gasket adopts fireproof stainless steel wire and flexible graphite gaskets.The stem packing adopts flexible graphite to ensure no leakage in case of fire.

- Q:Long story short, have a 2001 acura tl had a rough idle/ no start issue. figured out by disconnecting vaccuum from the throttle body the idle was fine with the TB pulling air through the disconnected hose port. The hose i disconnected leads to the purge valve solenoid. I removed it and it is closed (no air flow), restarted car with hose disconnected and solenoid still harnessed in (still closed). Just need more info on the function of this thing and what it should be doing.. Can i bench test it with +12V and ground on the two pins? Thanks in advance.

- Q:One of the zone control valves in my heating system does not appear to be working. The thermostat is calling for heat, but no water is flowing. If the other thermostats call for heat, the valves seem to open as the pipes above the valve get hot from the water flowing through. The one that appears busted gets luke warm at best. All 4 valves in the system are fed from the same pipe, and the failed valve is the third in the series of 4 along the pipe (and #4 flows fine) so it doesn't appear to be something in the feeder pipe.Is there anything I can do to try and fix the existing valve, can I replace the valve myself? Would replacing the valve top of the valve (the green/gold portion) possible fix the issue (maybe a problem with the operation of the piston? Is there anything I ahve to do before removing the valve top aside from removing power to the valve?
- You would need to isolate the valve from the line, and depressurize the system, and I would think that turning off the heater and letting the temperature fall would probably be necessary if you don't want a relief to lift in the boiler. If you make a mistake here you have a very good chance of being scalded to death, or permanently scarred. Also, you may need to sweat and braise the new valve with a torch, so you had better be sure you know what you are doing and don't burn your house down.
- Q:i was thinkin i needed rings cause my car was smokin like hell and had a bad compression test on one cylinder. anyways i got the head off and my valves are caked with black **** all down one side and the others are completely white. i dont know if when the car turns off if they're supposed to seal but four of them were about a quarter inch off the head. before i tested everything i was smokin like hell and barely runnin and you could hear a knockin sound in the exhaust at the rear of the car. could the head be the problem or still sound like rings??
- thats the oil being burned...its either bad rings thats why ur burning oil or bad valve guides...a ring will fail first before the guide
- Q:My 91 GMC Van has an Idle Control Valve that is unplugged, but the van still runs great. Will the valve being unplugged, result in harm to my vehicle?
- As long as the eng check light isn't on then it will harm nothing. If the light is on but the van runs good it's because the computer is running in a fixed parameters ( emergency mode ) and it's not running at top potential.
- Q:I have a stainless valve I want to install in a copper domestic water line. My concern is: are the two metals compatible? Are stainless steel and galvanized steel compatible?
- I presume you have a threaded ss valve. It can be connected to a galvanized threaded pipe or threaded fitting. The ss valve can also be connected to copper pipe by using a male x sweat brass adapter (threaded one end, plain for soldering on the other). Brass will prevent problems from electrolysis. On threaded joints use teflon tape, or in the case where the pipe carries fuel oil, use pipe dope.
- Q:One of my valves leaks a small amount of water through the valve and into the water line. why would it leak and what do i have to do to fix it. the valve is a rain jet valve. i would like to fix it without having to remove it from the valve box. inside the valve box there are 8 valves and they are glued in and i dont want to have to remove all of the valves and box.
- Sounds okorder ), and so sometimes its almost easier to replace the whole thing. The rain jet valves definitely aren't the best quality either, so if I were you I'd get a better one just to make sure it is going to work for a long time.
- Q:anyone know .. if the 5.7L Hemi 2003 has a egr valve?
- it might be on the passenger side on the valve cover
- Q:what is engine valve timining ?
- The valve's are in the head or head's and they need to be lined up with your crankshaft in order for the engine to be in time , if they was'nt in time with the crank they would hit at the wrong time and your engine would be junk.
- Q:IT USUALLY TAKES 2 SECONDS TO START THE MOTOR. NOW, IT TAKES OVER 40 SECONDS AT 7 AM. IT ALMOST KILL THE BATTERY. IF YOU PARK FOR 1 HOUR, 2ND START TAKES 10 SECONDS. IS THIS HAPPENING BECAUSE THE VALVES NEEDS ADJUSTING? HOW AND WHAT IS THE EASY WAY OF VALVES TUNE-UP?
- MY MECHANIC TOLD ME: AT 9000 MILES, SCOOTER IS DUE FOR VALVE ADJUSTMENT. EVERYTHING ELSE SHOULD BE OK. 1] WAIT UNTIL MOTOR COOLS OFF 2] REMOVE PLASTIC VALVE COVER 3] LOOSEN RIGHT FENDER TO GET EASY ACCESS TO VALVES 4] USE 8 MM SOCKET TO TAKE OFF THE FOUR VALVE COVER SCREWS 5] USE 10 MM SOCKET TO TAKE OFF THE LAST TWO NUTS 6] REMOVE ALUMINUM VALVE COVER 7] PISTON MUST BE FIRST COME ALL THE WAY UP BEFORE ADJUSTING VALVES 8] CHAIN AND DISK HAS 3 HOLES, SET HOLE ONE UP, HOLE TWO DOWN, AND HOLE THREE TO THE LEFT [ IN THE MIDDLE BETWEEN THE TWO VALVES. 9] MUST HAVE A GAGE FEELER SIZE 3/1000, AND 4/1000 $7 SET AT ADVANCE AUTO 10] USE 9 MM SOCKET TO LOOSEN THE TOP INTAKE VALVE NUT USE GAGE SIZE 3/1000 ON TOP OF VALVE. ADJUST VALVE SCREW, NOT TOO TIGHT, AND NOT TOO LOOSE HOLD THE TOP SCREW WITH A PLIER WHILE TIGHTENING THE TOP NUT WITH 9 MM OPEN WRENCH. MAKE SURE THE NUT IS GOOD AND TIGHT. MINE WAS MOVED TO SIZE 7/1000 MM, THEREFORE, IT WAS HARD TO START. 11] USE 9 MM SOCKET TO LOOSEN THE BOTTOM EXHAUST VALVE NUT USE GAGE SIZE 4/1000 ON TOP OF VALVE. ADJUST VALVE SCREW, NOT TOO TIGHT, AND NOT TOO LOOSE HOLD THE TOP SCREW WITH A PLIER WHILE TIGHTENING THE TOP NUT WITH 9 MM OPEN WRENCH. MAKE SURE THE NUT IS GOOD AND TIGHT. MINE WAS MOVED TO SIZE 2/1000, IT WAS HARD TO START. 12] HOOK THE GROUND WIRE, AN CHECK IF IT IS EASY TO START 13] ONCE IT HAS GOOD START, PUT THINGS BACK IN REVERSE AS THEY WERE. 14] FIRST PUT COVER AND ALL SCREWS HAND TIGHT ONLY, THEN TIGHT THEM GOOD. I STARED TIGHTENING THEM ONE AT A TIME, THEN THE LAST ONE WOULD NOT FIT I HAD TO LOOSEN ALL OF THEM AND GET THEM ALL STARTED AND HAND TIGHT FIRST. 15] ADVANCE AUTO MAY LET YOU USE SOME LOANER TOOLS 16] PUT EVERYTHING BACK TOGETHER AND YOU READY TO GO FOR 5000 MILES. GOOD LUCK, WERE YOUR HELMET, AND DRIVE CAREFUL. TRY NOT TO DRIVE IN BAD WEATHER WEATHER LINK: www.spc.noaa /
- Q:What is the functional difference between the following:1. Blow Off Valve2. Dump Valve3. Bypass Valve4. Diverter Valve
- My Dive save gave me the prospect to aim on the I3 interior the pool. Any sturdy dive save could. that's high priced kit which you will have for an prolonged time. It needs to in good condition authentic and paintings for you. besides, cooperative dive shops benefit a lot greater in a satisfied customer than they lose by applying letting you are trying on the BCD. I for you may t walk right into a dive save with out popping out with greater kit. LOL
