200X Pressure relief valve
Product overview
Adjustable relief valve is a pilot-operated relief valve, which consists of hydraulic control valve main valve and relief guide valve. The change of outlet pressure of main valve is magnified and controlled by the guide valve to control the action of main valve disc. It is a commonly used pressure control valve. The valve is mainly used to relieve the pressure of water supply network or building water supply system so that the downstream pressure remains a set value without any change of upstream pressure or other factors.Changes in downstream water usage.
