   A, RX series oil sealed plug valves
The 1980s, China s gas is mainly artificial coal gas;
Artificial coal gas has more impurities and the "gas glue", the original deed of traditional style with a single gate valve become

increasingly unable to meet the water needs of gas conditions, the prevalence of these valves "off loose" and stem bite problems, we

refer to Japanese technology developed by the RX series of gas oil sealed plug valves, loose and off to solve the problem of stem

killed.
Two, RZ Series Parallel Gate Valve with gas
With the development of gas and gas plant after another establishment, a larger and even large nominal diameter of the gas-specific

valve, RZ Series Parallel Gate Valve with gas for artificial gas formed to solve the given problem, the maximum pass diameter up to

1600mm. http://bengfa.gtobal.com/map.html
1, parallel to the Gate Valve opening and closing process can scrape off the sealing surface of the "gas glue" to solve the gas

impurities affect the adhesion of the valve sealing surface in sealing a big problem;
2, equipped with a protective sleeve valve stem, so that stem from "gas glue" of erosion;
3, the lower valve with a discharge hole side cover, you can clean the bottom of the garbage falls valve chamber;
4, full-bore design flow resistance, but also through the Pig;
5, the valve body using a specially designed "frame rib cage" valve to reduce the overall weight, increased strength and stiffness of

the shell;
6, RZ series gas valve selection of gray cast iron housing, low price; seventh, closed the series with the gate open and close indicator

allows the operator a clear understanding of the state in which the valve.
Three, RQZ series of nodular cast iron gas system with parallel Gate Valve
As China s natural gas into the town, the author and Gas Corporation, Shanghai, Suzhou City Gas Equipment Gas Valve Manufacturing

Co., Ltd. According to the characteristics of the system has developed RQZ ductile iron gas with parallel Gate Valve, the valve

retaining the RZ Series valve features, the choice of materials to enhance the wear resistance of the valve while the pressure level to

the high B grade.
Fourth, the butterfly
Lighter than the above types of butterfly valves, large diameter, lower prices in the early 1980s part of the Gas Company has – degree
Valve Burner
of use of butterfly valves, after a decade or so of use, generally considered ineffective. First, pay the isolation valve seal width is too

narrow, likely to cause the valve closing process too far, or not in place, affecting the seal; second valve chamber in the middle of the

valve, flow resistance, could not by the cleaning device; third, As the seal to pay in – in part of rubber or PTFE, easy to damage in the

gas erosion or loss, life is short. Practice has proved that in addition to a special place, should not be used on a gas pipeline butterfly

valve, butterfly valve has been used a number of gas companies are (or consider) the replacement of other valves.
Five flat gate
Gas pipeline flat gate valve is common in recent years began using the valve, full bore when the flow resistance is small, both sides of

the seal by the rubber O-ring PTFE or pressed to form the gate, the valve in the closed or opened can not be done in the chamber

without gas, not user-friendly repair quickly determine when the valve is locked, no gas to reach the cavity opening and closing

torque is rapidly increased; some manufacturers made of necking, columns such as DN200 diameter, inside diameter is only 150mm,

with particular attention to the user. Therefore, the flat gate-level system for low pressure, nominal diameter smaller occasions.
Six, TRZ series elastic sealing gas valve
TRZ series elastic sealing gas valve is different from the flat gate valve of a gas-specific. Characteristics of the valve ball valve with

resilient seat fixed structure similar to the gate on both sides seal seat with flexible floating structure, the sealing surface in the

opening and closing and opening and closing process is always close together, but also to pay compensation sealed wear, high-

pressure-level system for the occasion; the valve in fully open, fully closed when the valve chamber can be achieved without gas,

even if complete diffuse gas remaining in the valve chamber, the valve cavity still no pressure.
Seven, RQ series ball
RQ Series fixed ball valve is specifically designed and manufactured for the gas industry, the various types of ball valves combines the

characteristics of domestic and foreign, according to China s national conditions developed for long-distance gas lines, city gas facilities

off valve.
The following advantages:
1, fire resistance, fire burning hot seat of the PTFE sealing materials, sealing in all metal parts of the seal seat and can form metal to

metal sealing structure to prevent gas diffusion media, to prevent the disaster continue to expand;
2, anti-static, ball valve in the open and close during the formation of static electricity can easily ignite the gas, static electricity into

the ground ball to ensure the safety of equipment;
3, limit lock, ball is rotating mechanism, likely to cause a 360-degree rotation, in addition to the limited spaces outside agency can be

locked again to prevent the operator misuse or unauthorized operation of the operator caused the accident; fourth ball stem stem

seal design with anti-shock device, and uses special O-ring seal, valve torque than similar small, easy operation, open and close quickly.
Eight, Used for emergency shut-off valve regulator
Used for emergency shut-off valve regulating gas distribution system is an important safety device. Emergency shut-off valve is in the

upper or lateral valve equipped with an emergency tripping device, but also connected with the regulator body as a whole, but also

connected with the filter as a whole, its role in the voltage regulator failure, resulting in over-pressure or emergency shut-off after loss

of air pressure to ensure safety. A large number of natural gas used in cities, improve the pipe network pressure tier system, the

failure of the regulator city will have disastrous consequences, the domestic gas industry, which more and more attention. Domestic

product has not yet selected a certain trend, imports, joint ventures, domestic, is difficult to distinguish good and bad, to be used

with caution. RAQ series gas emergency shut-off valve with filter as a single entity, novel compact structure, high sensitivity, set the

gate in the overpressure (300mm/H2O) and loss of pressure (180mm/H2O) quickly cut off the gas supply regulator to ensure the

safety of users.
Nine, emergency gas shut-off valve
Gas boiler, gas conditioning, gas equipment in the event of gas leaks or other disaster, the emergency shut-off valve quickly cut off

the gas source, to prevent the disaster expanded. Currently the emergency gas shut-off valve in the country is not yet universal,

valve businesses
As environmental awareness and enhance safety awareness, as well as the development of gas, gas emergency shut-off valve must

get people s attention. Gas emergency shut-off valve is to protect the security nature of the valves, and automated monitoring

equipment with machines, execute commands off valve, so the emergency gas shut-off valve is electrically operated valve, according

to available information there are two types reflect the type of valve, a class is the solenoid valve, one is electric valve. As the

emergency shut-off valve for high gas, primarily fast, sealing, flow resistance, caliber security and other specifications, the existing

solenoid valve, electric valve has some defects, can not meet all its requirements.
Ten, the gas valve
Storage and distribution of gas compressor stations often need to configure the check valve to prevent backflow of gas into the

compressor. Water check valve in the gas industry has been eliminated, generally the main drawback is that the gas valve with the

compressor valve plate reciprocating motion and vibration, collision with a large body of sound, easy to damage the valve plate; The

second was sealed is poor. R Series gas valve has solved these problems. The family will pay the other valve sealing valve 90 degrees

to 75 degrees, the valve plate to the valve seat to form – a natural pressure, while valve plate structure coupled with the outer

balance weight can be adjusted to solve the noise problem ; pay to switch to PTFE seals to improve sealing performance, put an end

to the "return air" phenomenon, R-type gas valve inception more than ten years ball with good effect.
