The valve maintains a preset downstream pressure, regardless of upstream pressure or flow

fluctuation. The main valve is controlled by a pilot valve, which makes the main valve modulating

to maintain the downstream pressure.

The main valve comprises valve body, diaphragm, stem assembly, and seat. The valve is

separated by diaphragm into two chambers, up and down. The upper chamber is control

chamber, and down chamber is flow through chamber. The valve stem is driven by diaphragm

up and down, and driven force comes from the differential pressure taken by two sides of

diaphragm.

Q: the rest are hot, the living room outside all the heating pipe valve closed, the living room heating is still not hot, after the water for a while hot, and cold: You just put the living room off the water inlet valve, open the drainage valve with backwater top a try

Q: Where is the Shandong valve? How about joint valves in Shandong?: To find Shandong valve manufacturers, Shandong better valve manufacturers are in Weifang, find the valve factory is also simple, direct search "Weifang valve" is

Q: What are the valves at home?: Valve used in the family is commonly used, the following are several:On the water pipe are: total table of the ball valve (32mm), in charge of the (25mm), as well as for the toilet, washbasin, water heater angle valve (20mm).Other commonly used gas pipelines, valves, pressure reducing valves and the like.

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: What does the whole copper valve mean?: Except the handwheel, all the material of the valve body is copper

Q: How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?: Which standard does the wall thickness refer to? ASME B16.34?Design and calculation depends on what standard you chooseOr have you found the standard yourself and read it yourself?You choose what standards, design parameters reference, interpolation or fitting, how to fit, are their own sayI wrote a excel series of valve calculations, it does not take long to writeFor long-term useIn order to improve efficiencyOr write your own database program is better

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: Valve pressure grade division: Valves are classified by pressure:Vacuum valve - valve with operating pressure below standard atmospheric pressure.Low pressure valve - nominal pressure PN is less than 1.6MPa valve.Medium pressure valve - nominal pressure PN 2.5~6.4MPa valve.High pressure valve - nominal pressure PN10.0~80.0MPa valve.Ultra high pressure valve - nominal pressure PN greater than 100MPa valve.
