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: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.

Q:the valve to an electrical signal, with this signal to control other components, ask: what valve?: It seems that this is not a valve, it should belong to the flow switch

Q:What's the caliber of the valve 1/4?: 1 inches is equal to 25.4mm, 1/4 how big, count it yourself.

Q:1/2, what does 1/4 valve mean? I don't understand. What does this number mean? Have a valve to introduce me, do not copy a pile of online introduction, I want to concise: I have to answer a simple 1/2 1/4 is American Standard valve diameter to the national standard to calculate it is 1/2=DN15 1/4=DN8Also on the valve size of the meaning of the Wenzhou essence valve factory for you to answer

Q:Where is the Shanghai valve? What brand is good?: To tell the truth, I think the Shanghai Yang Yi valve is good, in product quality, as well as product packaging are very good, especially after sale service, are free of charge

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

Q:Is the heat jacketed valve fitted with flanged flanges?: Insulation valve is the standard valve, just in order to ensure the link bolt flange to super space, usually a large ball than normal level, such as the use of the path is DN80 flange, flange is DN100, so is the standard, but the size of flange connecting with other valves are not the same.

Q:What are the ten major brands of China's valves?: If you want to buy fluorine valve, you can go to Shanghai corrosion-resistant valve group Co., Ltd., and what questions contact me?!

Q:What valve does the high pressure by-pass valve DN254 * 800 belong to?: You want to ask the classification or valve DN254 mean?. The data you gave was incomplete. No answer.
