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: Remove the handle and lever the stem rotation with a wrench,: First you know what valve you need, or you know where to use the pipe material, so you do not need to understand the valve material.

Q: Which industries need valves?: 3., the other side of energy development is energy conservation, so from the perspective of energy conservation, it is necessary to develop steam traps, and to sub critical and supercritical high parameter development;4., the construction of power stations to large-scale development, so the use of large diameter and high pressure safety valve and relief valve, but also need to quickly open and close the valve;5., for the needs of complete sets of projects, the supply of valves from a single species to more varieties and specifications. The valve required for an engineering project is growing with the full availability of a valve manufacturer.In the next few years, the overall trend in demand for the valve for the upward trend, the valve of this large volume of industrial supplies, its demand in steady growth. Among them, the demand for a larger number of valves in turn are: ball valve (15.5%), cut-off valve (12.9%), safety valve (12.5%), gate valve (12.5%), butterfly valve (10.6%), regulating valve (8%) and check valve (6.1%).

Q: How about the quality of FITOK valves?: It's made in China. It's also made of foreign brands!Swagelok, Hoke, Parker, these three are foreign brands!

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 are the valve types H, F, and Y? What are the meanings of these 3 letters?: Please refer to "JB/T308-2004 valve model preparation method"Sealing surface material codeH Cr13 stainless steelF fluoroplasticY cemented carbide

Q: If the valve in the pipeline throttle, such as open and open 50%, the valve before and after the pressure of how to calculate, how the flow changes?: the preset pressure after the valve, thus maintaining the dynamic pressure balance valve, and non compressible medium, mainly for the purpose of regulating the flow, especially in the petrochemical industry, power industry, if the specific calculation of a valve is more difficult, but a lot of data will provide the valve valve opening and flow of the corresponding graph, the landlord is really interested in learning more, can go to the Xinhua Bookstore to find the valve selection manual valve related content, which will introduce calculation method.

Q: The valve has a clear opening and closing sign. What does this sentence mean?: Not only on the valve is enough to mark, here means that at the scene can see the installation of the pipe network on the valve open or shut?!

Q: How do you calculate the flow of the valve?: Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.
