The products are widely used in water source projects, urban water supply and drainage, sewage treatment, eletric power, petroleum, petrochemical, heat supply, shipbuilding, medicine and metallurgy industries. Equipment are used for regulating or cutting off media in pipelines. Suitable media include water sewage, sea water, air, foodstuff and oil. Suitable for gear operators, electric and pneumatic control actuators.

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: What are the meaning of the cast rigid gate valves z41h-16c?: According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== flange connection1== rigid single gateH== sealing surface material: Cr13 stainless steel16== pressure rating: 1.6MPaC== body material: carbon steel

Q: What is the difference between an elastic gate valve and a rigid gate?: General rigid gate used in the temperature is not too high, the pressure is not too large occasions, flexible gate used in high temperature, high pressure, or relatively high sealing requirements.Valve closed, the sealing surface can only rely on medium pressure to seal, that is to rely on medium pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing.

Q: Does the tap belong to a stop valve or a gate valve?: Most faucets are stop valves,Part of the faucet is plug valve,Hot water nozzles are almost all plug valves.

Q: What's the difference between the knife gate valve and the stop valve?: Minor force needed for opening and closing.Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is better.The valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for many kinds of occasions, the valve rod valve the dark bar gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume.

Q: What is the allowable leakage rate of the gate valve D?: In GB/T 13927, the leakage rate of the valve is divided into 10 grades, namely: A, AA, B, C, CC, D, E, EE, F, G class. And stipulates that when the order contract does not specify, the metal sealing valve according to D requirements.

Q: What is the wedge type gate valve wedge is what mean: It can be used on high pressure gate valve. Wedge gate and elastic wedge gate, gate and double gate. A, elastic ram. A circular groove is machined on the vertical bisector surface of the gate so that the gate plate has a certain elasticity. It is this elastic deformation, the gate is closed, the compensation gate sealing surface and the valve seat sealing surface between the wedge angle deviation, the arrival of good agreement, to ensure the sealing. Resilient gate valve sealing surface reliable. Applicable to a variety of pressure and temperature of small and medium-sized gate valve, requiring medium containing solid particles to less, in order to prevent congestion in the gate ring groove, affecting the flexibility of sealing.

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: Acid resistant alkali valve gate valve: D is small in shape and beautiful in appearance.E operation is simple and labor-saving.

Q: Gate valve z41t what does that mean?: According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = connection form: flangeT = sealing surface material: copper alloy
