Q: What is the normal temperature on the valve?: 3. classification by operating temperature(1): ultra-low temperature valve for medium temperature of t< DEG C; 101 valve.(2): used for medium temperature valve operating temperature 101 C = t = 29 C valve.(3) at room temperature for medium temperature valve: the valve 29 <t<120 DEG C.(4) the temperature valve for medium temperature 120 = t = 425 DEG C valve(5) high temperature valve: valve used for medium temperature t>425 degrees celsius.If it helps, see it

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: So how does the valve turn on?: The handle of the valve is opened along the pipe and perpendicular to the pipe

Q: Who knows which kind of water valve is good?: Classification of domestic valves:pipeline valveBathroom valves, kitchen valves, etc faucetsPipeline valve is generally sealed with rubber valve is better, rubber sealed valve sealing performance is very good and durable;Bathroom valves, kitchen valves and other faucets will use copper into the Dian valve, copper valve is not rusty, durable. ,Hope to help you.

Q: What is called protective valve, and other valves what is the difference?: Protection valve should be in the air defense valve, can be copper gate valve. (according to the specific use of civil air defense requirements, design institute does not count).2, while the protection valve should be a locking device with the valve, not the general valve can be replaced.

Q: What does "DN15" mean? What does "PN 16" mean?: Valve nominal diameter 15mm, valve nominal pressure 1.6MPa

Q: The total valve of my natural gas was closed by the attitude I tried. Now I can't open it. I need to use gas. Who knows how to drive it? What skills do I have? I'm talking about the main valve.: General domestic weather is more ball valve, counterclockwise turn 90 degrees can.

Q: What is the difference between a stop valve (a power station valve) and other valves?: Power station cutoff valve advantages editor1., the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section.2., simple structure, small size, light weight.3., reliable and reliable, the current gate valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used.4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.5., easy maintenance, simple valve structure, sealing ring is generally active, disassembly and replacement are more convenient.6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface.7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.

Q: Why is the valve on the pipeline not the same size as the pipe, and how much of a crude pipe can be given? Thank youI'm sorry, I didn't make it clear that when doing pipe work in the factory, for example, 60 of the pipe, and in this pipeline to install the valve to choose DN50, and so on.: The valves on the pipe should be of the same size, which saves costs and reduces head loss.

Q: Excuse me American Standard pressure test valve GB standards are much ~ is how much valve pressure can play much pressure? Thank you: The standard is different, the test is not the same, what kind of valve you, a domestic valve only do stress testing, in fact, the pressure can generally be guaranteed, many are bad at high temperature or life testing above
