Product Description:

pipeline ball valve-reduced bore High-performance

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.
)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
)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.
)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.

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.
)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.

()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.
)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:How to adjust valves?

Q:exhaust valves material & dimensinons?
Most valves are made of forged steel. The dimensions depend on what car. You can get a factory manual for any car. Call a motor shop to order them. Don't try to make them yourself.
Q:Help with a leaky valve..
If the leak is at the valve stem tighten the packing nut just below the stem, if leak is on either end of the valve tighten them with wrench also, if that doesn't work remove entire valve after shutting of water at main supply remove valve and take to hardware store to get a replacement valve, they will beable to tell you how to reinstall properly.
Q:I need a one way filler valve?
go to a tire store, get a tire valve, then you can fill it with any kind of air pump.
Q:Can i smoke pot with and artificial valve?
I don't smoke anything. So pot was not an option for me. With that said I really do not have a problem with those that choose to do pot. I feel the same way about it as people that smoke. Please don't do it in my house, or in a confined area where I can't get away from it. I really do not want it around my kids. I think pot is safer then alcohol. I have known people that smoked pot. The majority of them did it to relax which meant they were hanging out at home. I feel that it should be legalized as that would kill a HUGE crime industry. Not much point in smuggling it over the borders or having secret deals with individuals when that person can run down to the local convenient store and pick it up. It could also be extra income for the governments as they could profit off it. I don't think it should be done while children are being watched. Like any substance, regardless of how mild it may be, it can impair your judgement. =)
Q:how much would it cost to fix a busted valve in the head on a 1995 ford probe?
When you say busted valve, do you mean a bent valve, or a broken valve? if you meant broken valve, i guarantee you my friend, that car is something that you do NOT want to invest your money into. a broken valve can cause and may have already caused all sorts of further damage. this can include exhaust fumes leaking into the cooling system and over-heating the engine, engine cylinder or gasket leaks causing oil to mix with coolant, broken timing belt, blown head gasket, and the list goes on. i HIGHLY recommend you stay clear of a broken valve. if you meant bent valve, this is generally not as serious, but is something to be very cautious of. the best way to check for a bent valve is to have a compression check done. a mechanic can do this, or you can do it yourself if you buy a compression checker. if the valve is indeed bent, the first thing you will want to find out is WHY it got bent. generally this happens because the timing belt slips or the valve has a leak from being stuck open. if this is the case, you might be looking at coughing up $300, maybe a little more, maybe a little less. but before dumping your money on fixing a bent valve, you want to get a professional inspection and make sure that this bent valve didn't cause damage to anything else. i hope this will help you with your question and with your decision on buying or not buying the car. good luck!
Q:Water Turnoff Valve will not come off?
basically component to the diverter valve is broken, besides the undeniable fact that, it extremely is terrific to replace to total diverter stem. If their are 3 handles, you are able to do away with the middle one devoid of turning the water off. Then convey total stem with you to the ironmongery shop. There are quite some video clips on youtube and different ironmongery shop factors of interest in case you like help. good success.
Q:Toilet wall valve is not working properly?
Check your fill valve (inside the tank) first. If it appears to be working properly, turn the water off outside the house, drain the tank, take the filler tube ( from the valve to the bottom of the tank on the outside) loose at the valve. Remove the valve and inspect for obstructions, such as calcium and or lime deposits. You may need to replace the valve as they will occasionally wash out over time. Reverse this process to put everything back together, and be sure to wrap the male threads on the supply line (pipe sticking out of the wall) with teflon tape.
Q:Eclipse gst blow off valve?
if you want it to operate properly the yes you will need it. The valves are also adustable but you need a tech manual to and special tool to do it propperly dont just guess at its setting rather know it. I assume the picture i looked at was your engine. Unless you like taking chaces i would recomend you put your timing belt cover back in place. If anything should get in there between your t-belt and gears or pullys the belt could be damaged and if it does get damaged you could damage the valves in the event of t-belt failure. I know people like to see the belt and gears moving and if that is what you are wanting i would suggest installing one of the clear t-belt covers that are available. unfortunatly i do not know who makes them. if you cant find out go to a car show and talk to gear heads that have them on there cars.
Q:Is valve standard of API and ISO same?
the name itself suggest that it isn't. BSP covers only pipelines but ISO is a standard concerning different materials, processes, programs and quality policies.
