A pressure control valve is a device used to regulate the pressure of a fluid or gas in a system. It is typically a mechanical valve that is designed to automatically adjust its opening or closing to maintain a desired pressure level in the system.
When the pressure in the system exceeds a preset value, the pressure control valve will open to allow fluid or gas to escape, reducing the pressure. Conversely, when the pressure drops below the desired level, the valve will close to prevent further loss of pressure.
Hydraulic Pressure Control Valve
Hydraulic pressure control valves use hydraulic fluid to control the pressure in a system. They are typically operated by a piston that opens or closes the valve to regulate the flow of hydraulic fluid.
