Hydraulic Check Valve
Areas of Use
Safe and Controlled Flow Management for Fire Protection Systems
Hydraulic Check Valves are automatic, hydraulically operated valves designed to prevent backflow in fire pump discharge lines, providing a safer and more reliable alternative to conventional check valves. When the outlet pressure exceeds the inlet pressure, the valve closes smoothly without causing water hammer, protecting critical components of the fire protection system. When the inlet pressure rises above the outlet pressure, the valve opens in a controlled manner, ensuring safe and continuous flow.
This operating principle helps prevent sudden pressure surges that can occur during pump start-up, thereby safeguarding pumps, pipes, and fittings. With its robust body construction, low maintenance requirements, and long service life, the Hydraulic Check Valve is ideal for use in fire water systems. Its soft opening and closing action enhances system efficiency while extending the lifespan of both the pipeline and the pump.
