Q: High and low pressure valve is how to distinguish?: Ultra high pressure valve nominal pressure PN = 100MPa; high pressure valve nominal pressure PN10.0MPa ~ 80.0MPa; medium pressure valve, nominal pressure of PN2.5MPa ~ 6.4MPa; low pressure valve, nominal pressure PN is less than or equal to 1.6MPa

Q: What does the 4 point valve mean?: The caliber is DN15's valve. What valves do you need?

Q: such as gate valve, three way plug valve: The pressure gauge shall be fitted with three way cock.The safety valve does not install any valves and other components on the boiler. Can be installed in the pressure vessel, but when the equipment is running to handle and open the valve, plus seals, hang the obvious mark, a warning can not be closed.

Q: HH valve company in the United Kingdom, how about the valve?: Our factory boiler has this brand of valve, used for many years, has been no problem, really good.

Q: What is the flow medium of the valve?: What is the valve. If the water through the valve, the medium is water. I hope I can help you.

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: There is a rectangular hole in the valve core, which the heating company repairman gives to the bolt. Rest assured, I do not want to heating, but my indoor temperature is low, I suspect that the repairman mischief, deliberately give me lower temperature: The heating valve refers only to a radiator system accessories, is a type of valve, the valve commonly used heating system on the market is mainly divided into: gate valve, ball valve, safety valve, balance valve, globe valve, regulator valve, relief valve, pneumatic control valve.

Q: How does the valve rust die?: Go to the hardware store to buy derusting lubricant, W40 is fine.

Q: What's the advantage of using three way valves?: Three way valve generally has a cut-off, regulation, diversion, and prevent counter flow, voltage regulation and overflow and other benefits, because of its benefits more, so the use of the three valve is extremely extensive, in the valve industry is also very important.
