500X Pressure holding relief valve
Product overview
Pressure relief/pressure holding valve is composed of hydraulic control valve main valve and pressure relief guide valve. It is a common pressure control valve to open and close the main valve through the opening and closing of the guide valve.
The valve is suitable for relieving pressure of water supply network or building water supply system, so that the system pressure is not higher than the valve set pressure value, to ensure the safety of the system pipeline or maintain the minimum water supply pressure of the pipeline in front of the valve.

Hydraulic control, without external driving force;
The main valve has only one moving part, so the failure rate is low;
Diaphragm structure, no friction, high control sensitivity;
The relief pressure of the valve is adjustable;
Once the pressure of the pipeline system is less than the relief pressure, it can be quickly closed and zero leakage can be realized.
