  • Cast Steel Pump Control Valve

    Cast Steel Pump Control Valve

    We supply Cast Steel Pump Control Valve.The HISPEED® Pump Control Valve is a designed for installation on the discharge of booster pumps to eliminate pipeline surges caused by the starting and stopping of the pump. The pump starts against a closed valve. When the pump is started, the solenoid control is energized and the valve begins to open slowly, gradually increasing line pressure to full pumping head. When the pump is signaled to shut-off, the solenoid control is de-energized and the valve begins to close slowly, gradually reducing flow while the pump continues to run. Should a power failure occur, a built-in, lift-type check valve closes the moment flow stops, preventing reverse flow regardless of solenoid or diaphragm assembly position. The HISPEED® Pump Control Valves are designed for installation in the water supply connection to sprinkler, deluge, foam systems, or standpipe fire protection systems.The HISPEED® Pump Control Valve features a flange, easy installation and accessibility. We are expecting to become your long term partner in China.
