We are glad to give you our best service and our best products especially the gost steel gate valve.

And you can tell us if there is any requirement.

Q: How to find all kinds of mysterious valves of human body?: Many cell signal channels have been found, and if you can find each signal, the channel will be almost the same. That's the mysterious valve you want, but it's hard.

Q: What does the "PN" mark on the valve mean?: The valve will usually be marked with "DN.PN." these two signs,DN refers to the valve path, and PN refers to the pressure levelFor example: DN25, PN16Refers to the valve diameter of 25mm valve, the pressure is 16 kg (1.6Mpa)

Q: The difference between fire general valve and fire fighting special valve: Fire fighting valves are mainly signal valves and alarm valves and water indicators, etc., other gate valves, butterfly valves, pressure relief valves and filters are common valves.

Q: Symbols for all types of valves: In addition to the throttle valve (L) valve (H) valve (U) valve (Y) of the four types of valves, the other is according to the first letter of the easy to remember the four valve but also second word the first letter and the other valve is repeated with the first letter of a very good record I was just valve knowledge I hope to help you!

Q: What are the uses and differences of gate valves, butterfly valves, ball valves and other valves?: The use of the same difference, you can see the shape

Q: Which valve can play a good regulatory role?: A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.

Q: What valve does the high pressure by-pass valve DN254 * 800 belong to?: This is because the bypass valve is a special valve and other valve type theory.This is custom-made valves, generally no inventory, and may not have the material you need. So it needs to be customized.I remember the German HORA had the valve, but the price was sky high.

Q: I would like to ask commonly used water valve what kind of? What are the characteristics?: butterfly valveThe butterfly valve has the advantages of simple structure, small volume, light weight, only by a few parts. But only can rotate 90 degrees rapid hoist, simple operation, while the fluid control valves have good properties. The butterfly valve in the fully open position, the disc thickness is only when the medium flows through the power, by the valve the pressure will be very small, so it has better flow characteristics. Our company is mainly metal plastic butterfly valve, eccentric butterfly valve, butterfly valve, inlet butterfly valve, wafer butterfly valve and so on.Globe valveBall valve and plug valve is the same type of valve, only its closure is a sphere, the sphere rotates around the body center line to achieve the opening and closing the valve. A valve in the pipeline is mainly used for cutting, distribution and change the direction of media flow, the ball valve is a new valve in recent years has been widely using.

Q: What are the key valve enterprises in China? Mainly in those areas?: Chinese valve is mainly produced in Zhejiang, where Wenzhou, Shanghai there are a lot of Zhejiang valve in Wenzhou, but also Shanghai valve production, many are also Zhejiang boss, the key depends on whether you need what valve valve, the valve may be located in different regions is not the same

Q: Excuse me American Standard pressure test valve GB standards are much ~ is how much valve pressure can play much pressure? Thank you: Strength test is nominal pressure of 1.5 times, the test time is 5min, the test time, the valve body is not broken, no deformation, the valve is not leaking water, the pressure gauge does not drop to qualified. After the strength test has passed, the tightness test is carried out. The tightness test pressure is equal to the nominal pressure. The valve does not leak in the test time, and the pressure gauge does not drop to be qualified.
