Stainless steel pilot pressure reducing valve

Product Description

Work principle

The pilot pressure reducing valve is mainly composed of valve body, main spring, main valve core, main valve seat, piston, pilot spring, pilot valve core, pilot valve seat, pilot piston and adjustment spring. Twist the adjusting screw, compress the adjustment spring, open the pilot spool on the top, and the medium enters above the piston from the inlet side.
Since the piston area is greater than the main valve spool area, push the piston downward to make the main valve open, adjust the pressure of the spring by the pressure balance after the valve to change the opening degree of the pilot valve, thereby changing the pressure above the piston, and control the opening of the main spool to keep the pressure after the valve constant.
Pilot-operated pressure reducing valves use the hydraulic operating principle to achieve control. As a component for adjusting and throttling local pressure changes, the pilot operated pressure reducing valve reduces the inlet pressure to a certain set outlet pressure range, and then automatically maintains a stable outlet pressure with the energy of the medium itself.

Application field

Used for domestic water supply, firewater supply and other industrial water supply systems

Pilot operated pressure reducing valve pressure regulation step

1. First, close the gate valve in front of the pilot pressure reducing valve, and then open the gate valve on the pilot pressure reducing valve equipment to achieve the downstream low pressure state.
2. Rotate the adjusting screw of the pilot pressure reducing valve counterclockwise to the top position, remember not to rotate clockwise, and then close the valve behind the pilot pressure reducing valve.
3. Slowly open the gate valve in front of the pilot pressure reducing valve, knowing that the front valve is all open.
4. At this time, the valve of the pilot pressure reducing valve needs to rotate clockwise, mainly to adjust the outlet pressure to the required pressure.
5. If the outlet pressure is higher than the set pressure when adjusting the pilot pressure reducing valve, it is necessary to stop the following operation, and then readjust from the first step.
