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:I am a 55-year-old female going in for mitral valve replacement surgery, and I need to decide on which valve to get: bovine or mechanical. If you have any experiences or know anyone who's had either of these types of valves placed in their bodies, please elaborate on the experience. I want to know the pros and cons of each.Thank you.
- Hope this helps matador 89
- Q:hello!I'm designing a floor cleaner and for a water release system i was thinking of using a ball valve, connected to an actuator,however i'm not fully sure what to look for, and although I can buy the actuator and ball valve together, I'm not sure how to connect it to a motor and battery?If anyone can help my with this I'd really appreciate it!!Thank You!!
- it is going to be to long of an answere to bypass by, yet you have a often closed valve and a often open valve. So while air is provided, one opens and the different closes. you may artwork something out with that based how your set up is going to be. it rather is the solenoids i'm talking approximately.
- Q:ok, after lots of exploring around online and from some great answers from this site I have found the problem to my explorer. The torque converter solenoid mounting clip broke. thats it!! new question, do i have to take off the valve body to remove the solenoid. If so any tips? its way new territory for me. I hate automatics!!
- Yes. REMOVAL Disconnect battery ground cable. Raise and support the vehicle. WARNING: THE ELECTRICAL POWER SUPPLY TO THE AIR SUSPENSION SYSTEM MUST BE SHUT OFF PRIOR TO HOISTING, JACKING OR TOWING AN AIR SUSPENSION VEHICLE. THIS CAN BE ACCOMPLISHED BY TURNING OFF THE AIR SUSPENSION SWITCH LOCATED IN THE REAR JACK STORAGE AREA. FAILURE TO DO SO MAY RESULT IN UNEXPECTED INFLATION OR DEFLATION OF THE AIR SPRINGS WHICH MAY RESULT IN SHIFTING OF THE VEHICLE DURING THESE OPERATIONS. Remove the transmission fluid pan, filter, and gasket. NOTE: If a transmission has been disassembled to replace worn or damaged parts and the valves in the main control valve body stick repeatedly from foreign material, the torque converter must be removed and cleaned by using a mechanically agitated cleaner, such as Rotunda Torque Converter/Fluid Cooler Cleaner 014-00028 or equivalent. Unclip main control valve body wire harness. - Lift up on wire harness guide and protector and disengage the retaining pins from the solenoid clamps. Disconnect the six solenoid electrical connectors. (1) Disconnect the SS1, SS2, SS3 and SS4 electrical connectors. (2) Disconnect the torque converter clutch (TCC) solenoid electrical connector. (3) Disconnect the electronic pressure control (EPC) solenoid electrical connector. Remove the manual control valve detent lever spring. (1) Remove the manual control valve detent lever spring bolt. (2) Remove the manual control valve detent lever spring. Remove the low/reverse servo cover bolts. (1) Remove the low/reverse servo cover bolts. (2) Remove the low/reverse band servo cover and gasket. Discard the low/reverse servo separator plate cover gasket. Remove the low/reverse band servo piston and rod. Do not remove the two (gold) bolts specified. CAUTION: Support the main control valve body. Remove the 23 main control valve body (black) bolts. CAUTION: Support the main control valve body. Remove the main control valve body.
- Q:Anyone know what causes a heart valve to leak? I had surgery to repair mine (mitral) a few months ago, and now I have a very mild leak.
- The valve isn't closing securly. If that's what you went in for, maybe the surgery wasn't done properly.
- Q:so, im a day away from getting a 2002 748 and im super excited, iv always wanted a ducati, and i cant wait to have one of my own. i understand that ducks have a reputation of breaking and im prepared for it. I also understand the valves need to be adjusted every 50-100 feet :P all kidding aside i know every 6k miles they need to be adjusted. i dont know however how much it costs to have the valves adjusted. im sure it varys from shop to shop but a ball park quote would be really helpful just so its not a kick in the gut when i take it in for the first time. thanks
- Well first, you need to get them inspected, and they'll only adjust the valves if it's needed, even at 6k mile intervals, if your valves are still in spec or very close without lobe drag, they probably won't be changed, so check your bill and ask your tech directly if they were changed, some less reputable dealers may try to pull a fast one on you. If you actually needed ALL 16 shims changed, you're easily talking $1000 in labor, esp. on the 748/916 style heads, which have access ports on the heads instead of being able to remove the whole top of the heads like the newer DESMOQUATTRO heads, and are a PITA to work on because of it. The bad thing is that until recently (and they still need improvement) Ducati's quality control is lower than other manufacturers, meaning very inconsistent performance reliability, just from variances in manufacturing. If you get a GOOD tech to do the bike right in the first place though, not just valves but all-important TPS resetting, cam timing/belt tension, and balanced CO's in your exhaust, you will have a lot less headaches with your Duc.
- Q:Is there a relationship?
- I developed severe anemia when I was diagnosed with aortic stenosis. The Dr told me it was due to the damage the valve was causing my blood cells. He told me it also caused problems with my blood not clotting right and it would stop after my surgery. He was right and I haven't had problems since.
- Q:I saw some other answers. I figure the relief valve needs replacing, ok no problem, but exactly how much pressure are we talking about here? what is the correct procedure to shut this thing down to replace the valve?
- First if you follow the correct procedure the pressure is no problem. 1 Kill the power or gas to the heater-very important for electirc elements will pop if not done before water is drained. 2 Hook up hose to drain on the bottom and open it up to flow water outside of home. 3.Open hot water valve on tub and sink to allow water to drain after you shut off the main water supply. 4.Shut off the main water supply and let tank drain for an hour. 5. Use a pipe wrench to remove old pressure relief valve. 6 Pipe dope new pressure relief valve and install. 7Open main water vlve and close and remove water hose on drain. 8Let water flow out of tub and sink for 5 minutes after air has bled out. 9Turn system back on and be sure check for leaks.
- Q:freak accident broke the shutoff valve at my toilet, so first thing i did was shut the water off at the main shut off valve inside the house. then fixed the toilet shut off valve then went to turn the water back on at the house valve and it ran for a few seconds and that was it. so i then went to the main valve at the street to make sure it was open. it was open as well as all the others inside the house. still no running water. please help.
- did you ck the knob on the floor , make sure it is working sometimes the will strip out or the screw on the handle will come loose
- Q:Because I plan to remove mine on a 2000 Eclipse GT.Thank you all..
- The valves are not connected to the rockers, do you plan on removing the rockers or valves and why?
