The 500X pressure relief/pressure holding valve is mainly used in fire protection or other water supply systems to prevent system overpressure or maintain the pressure of the fire protection water supply system. Ensure the unobstructed circulation of the system to enable the valves to operate safely and reliably
A 200X Pressure Reducing Valve (PRV) is a hydraulically operated, diaphragm-actuated control valve designed to maintain a steady, pre-set downstream pressure regardless of fluctuations in the upstream (inlet) pressure or flow demand.
