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: The valve is rusty and can not be opened. What shall I do?
- Spray with rust removing agent on the rusty rotating parts of the valve. Then use an afterburner to make a tentative rotation. Open it and turn it in the opposite direction. And then spray rust remover. Repeat this several times, and the valve will probably open. Seriously rusty valve, if it really can not open, simply replace it.

- Q: Excuse me American Standard pressure test valve GB standards are much ~ is how much valve pressure can play much pressure? Thank you
- Strength test is nominal pressure of 1.5 times, the test time is 5min, the test time, the valve body is not broken, no deformation, the valve is not leaking water, the pressure gauge does not drop to qualified. After the strength test has passed, the tightness test is carried out. The tightness test pressure is equal to the nominal pressure. The valve does not leak in the test time, and the pressure gauge does not drop to be qualified.

- The boring actuator, that is, the pneumatic valve actuator, is described in the customs notesPneumatic valve actuator (three) separately presented. This device is equipped with a piston metal enclosure, linear motion of compressed gas generated by a needle perpendicular to the piston rod into the rotary motion, in order to control plug valve or other device with a rotary deviceSo the Shanghai customs will bring you the list backIn fact, the most important point of distinction or the actuator is pneumatic energy conversion in what form movement of the mechanical energy output, if it is a straight reciprocating, 84123100 is correct, if not belonging to the rotary linear motion, or radians, 841239 correct
