Product Description

In normal times, we all refer to the valves that control pressure as pressure control valves. Pressure control valves are sometimes referred to as pressure valves, mainly used to meet the force or torque requirements of the actuator. Including safety valve, relief valve, pressure reducing valve and sequence valve.

VICKERS pressure control valve working principle: the above downstream pressure difference △P is the power, controlled by the pilot valve, so that the diaphragm (piston) hydraulic differential operation, * automatically adjusted by the air, so that the main valve disc * open or * close or in the adjustment state. When the pressure gas entering the control room above the diaphragm (piston) is discharged to the atmosphere or the downstream low pressure area, the pressure value acting on the bottom of the valve disc and below the diaphragm is greater than the upper pressure value, so the main valve disc is pushed to the * open position; When the pressure gas entering the control room above the diaphragm (piston) can not be discharged to the atmosphere or the downstream low pressure area, the pressure value acting on the diaphragm (piston) above is greater than the pressure value below, so the main valve disc will be pressed to the * closed position; When the pressure value in the control chamber above the diaphragm (piston) is in the middle of the inlet pressure and the outlet pressure, the main valve disc is in the adjustment state, and the adjustment position depends on the joint control function of the needle valve and the adjustable pilot valve in the conduit system. The adjustable pilot valve can open or close its own small valve port through the downstream outlet pressure and change with it, so as to change the pressure value of the control room above the diaphragm (piston) and control the adjustment position of the square valve disc.
