FAQ

Open the pressure relief valve core hole with what
Attention to maintenance methods of eccentric hemisphere valve:1, eccentric hemisphere valve in the closed state, there is still pressure fluid inside the valve body.2 、 before repair, release the line pressure and make the valve in the open position.3. New parts should be cleaned before assembly.4. Remove the actuating mechanism from the support before servicing.5, non-metallic parts cleaning should be immediately removed from the cleaning agent, not long immersion.6, need to be cleaned by washing the wall after volatile cleaning agent (cleaning agent can not dip silk rub) for assembly, but not for a long time on hold, otherwise it will rust, dust pollution.
The valve nominal 1/2, 3/4 is how much?
The 1 point is DN25 mm1/2 is DN15 mm3/4 is DN20 mm
Is the water inlet valve good or the ball valve well?
The ball is good, recommended to install copper ball valve, not easily broken, rust resistant.It's not a bit of space to install valves at home. Moreover, the valve height is relatively high, the ball valve is that the handle occupies only the place, the handle to go, than the gate does not know how much space.We are specializing in the sale and installation of plumbing valves, and give you a professional answer.
Hello, I would like to ask the household tap water valve selection of stainless steel ball valve or brass ball valve is better, thank you
I have used two kinds, but stainless steel gate valve is better. Note that it must be made of stainless steel 304. I bought more than 300 yuan a gate valve. Total valve, no way to save money.
Water heater ball valve is not very easy to pull, why does it feel bad?
Use the hair dryer, hot air gear to blow for a while, slowly screw, a bit loose, continue to screw, you can completely screw, and more than a few twists and turns, long time does not move, it will be stuck
What does "41H" mean in the ball valve Q41H-16?
Q41H-16 in ball valve 41H stands forQ stands for ball valvesThe drive mode is manual (omitted)The 4 connection type is flange connectionThe 1 representative structure is the floating ball direct flow channelH: alloy steel sealing surfaceThank you, that's over.
I design water meter transformation, 50WPD table, the original table before the installation of 50 anti-theft valve, table after the installation of 50 of the globe valve; master let me put anti-theft valve into anti-theft gate valve. Switch the stop valve to the gate valve. I'd like to ask what kind of valve is appropriate Why? And I checked from the Internet that the ball valve is generally used for small aperture, this aperture range is how much? Why?No copy paste, thank you......
2, shortcomings:Because the main valve seat seal material is PTFE, it has almost all the chemical substances are inert, and the friction coefficient is small, stable performance, easy to aging, temperature range and excellent sealing characteristics of a comprehensive. But the physical properties of PTFE include high expansion coefficient, sensitivity to cold flow, and poor thermal conductivity. The design of seat seals must be carried out around these characteristics. Therefore, when the seal material hardens, the reliability of the seal will be damaged. What's more, polytetrafluoroethylene has a lower temperature range and can only be used at less than 180 degrees centigrade. Over this temperature, the sealing material will age. Consider long-term use, usually only at 120 degrees does not use.Its regulating performance is worse than the cut-off valve, especially pneumatic valve (or electric valve).Two, scope of application:Ball valves are used in petroleum refining, long distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries.
How to distinguish between cold water valve and hot water ball valve?
Used of hot water, soft, sealed, and used in cold water
