Q:What is the difference between gate valve and gate valve? Is it the same valve?: The valve is driven by the valve stem to make vertical lifting of the plate inside the valve body.Gate valve is the same reason. The gate valve and gate valve have steel gate, parallel double gate and so on.So the gate valve and gate valve are the same valve. It's just a different name.

Q:What is an inverted seal gate valve?: When the inverted sealing gate valve is fully opened, the sealing of the sealing is brought together, and the sealing effect is reduced, and the erosion of the filling to the fluid is reduced, and the service life of the filler is prolonged, and the possibility of leakage is reduced. Generally on the gate valve, stop valve has inverted sealing requirements.

Q:How about the model of stainless steel gate valve?: Stainless steel gate valve is divided into 304 stainless steel gate valve, 316 stainless steel gate valve, 321 stainless steel gate valve. The expression is: Z41H-16P.

Q:What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?: Cast steel flanged gate valve 25 pressure bore 250

Q:Why? God, can you explain to me in detail why?: Pump outlet, check valve, gate valve.Gate valve plays a regulatory role, is the main pipe. Such a sequence can ensure that the water flow during power failure does not cause damage to the gate valve.

Q:Gate valve is gate valve, gate valve specifications, model code is generally what?: Valve lock valve and gate valve. According to the code, the domestic valve type standard, valve type valve is composed of valve type, drive mode, valve connection, valve structure, sealing material, body material code to said gate type code Z.Gate valve: gate valve is one of the most commonly used shut-off valve, mainly used to connect or cut off the pipeline medium, not used to regulate the flow of media. A wide range of pressure, temperature and diameter is used, especially for medium and large diameter pipes.1, the main characteristics of gate valve(1) fluid resistance is small. The through hole of the gate body is straight through, and the flow direction of the medium does not change when flowing through the medium, so the flow resistance is smaller.(2) opening and closing is more labor-saving. When opening and closing, the direction of valve plate movement is perpendicular to the direction of flow of medium. Compared with the opening and closing more effort.(3) medium flow direction is generally unrestricted. The medium can flow in any direction from both sides and can achieve the purpose of switching on or cutting off. Easy to install, used in the flow direction of the medium may change in the pipeline.

Q:What do you mean by forged steel gate valves 800LB DN20 SW?: Forged steel gate 800LB pressure DN20 is by SW said socketweld (connection)

Q:What is plug welding gate valve?: Socket welding valve valve cover design in three forms. The first is forging steel bolt type valve cover, according to this design form design of the valve, the valve body and the valve cover bolt nut connection, spiral wound gasket 316 clamp flexible graphite manufacturing: seal. Customers have special requirements can be used when the metal ring connection. Second design form is the welded bonnet, according to this design form of the valve, the valve body and the valve cover with a threaded connection, welded seal. Customers have special requirements can be used when the third is connected through welding. Self sealing valve cover, according to this design form design of the valve, the valve body and valve cover with a threaded connection, pressure from the dense ring seal.The editing characteristics of 1 valve design and manufacture in accordance with API602 and ASME B16.34. tested according to API 598, marked by MSS-SP-25.2. full diameter or diameter shrinkage 3 rod bracket type 4 self centering sleeve type 5 pressure plate bolt connection, spiral wound gasket seal type valve cover nut connection, welded seal type valve cover and screw connect the internal pressure self tightening type valve cover 6 integral sealing seat 7 socket end with ASME B16.118. threaded end (NPT) with ANSI/ASME B1.20.19. valve can be transformed into the throttle type, needle type, ball type and type check

Q:What else, P54140V, 170V? What do they mean?: P work pressureP54 temperature at 540 degrees of work pressureThe pressure at P54 100 is 540 at the temperature of 100barV valve for chromium molybdenum vanadium steelP54 pressure 140V temperature at 540 DEG C for 140bar valve for chromium molybdenum vanadium steelP54 pressure 170V temperature at 540 DEG C for 170bar valve for chromium molybdenum vanadium steelFrom the JB/T4018 "valve type model preparation method"The standard unit is MPa, but it is usually used in bar

Q:Which is more expensive, bronze gate valve or brass gate valve?: The advantage of casting method is more obvious. The casting of stainless steel is much more difficult than that of brass.
