400 x flow control valve consists of the main valve, flow regulating valve, needle valve, pilot valve, ball valve, micro shape filter and pressure gauge of hydraulic control of system. Use of hydraulic automatic operation, control and adjust the opening of the main valve, made by the main valve flow rate remains constant.
400 x flow control valve with hydraulic control on our own efforts, do not need other devices and energy, easy maintenance, stable flow control. 400 x flow control valve is widely used in water supply network system of high-rise buildings, residential and urban water supply engineering.
When the valve from the inlet water supply, water flows through a needle valve in the main valve control room, and after a pilot valve, ball valve, from the main valve control room to export, the main valve in the fully open or floating state. Setting the upper master valve flow control valve, can be set in a main valve opening. Adjust the opening of needle valve and regulating valve spring pressure, can keep the main valve opening in setting the opening, and pilot valve to automatically adjust when pressure changes, the flow rate unchanged.
- Q:How about the valve?

- Q:What does valve 41F-40C mean?
- Incomplete model4 is the flange1 is the formF is seat material, fluoroplastic, ptfe,40 nominal pressure 40 kgC body material carbon steelFront also have to add valve category code, such as manual ball valve, Q41F-40C manual code is 0, but this 0 we don't write out, so only written Q41F-40C electric ball valve, Q941F-40C 9 represents electricGate valve is Z41F-40C
- Q:What is the term "Z41H-16C" on the line?
- Therefore, the opening position of the valve is determined by the position of the gate (i.e. the stroke).Z41H-16C closed, the sealing surface can only rely on medium pressure to seal, that is, only rely on the media pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing.
- Q:I used to do pumps, and now feel the future of the valve better, looking for a valve to do proxy, but my own economic strength is not good, I do not know if there is no possible to do?
