NRS metal-metal Gate Valve Manufacturers

We supply high quality Hispeed® Ductile Iron 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.

We supply Hispeed® Cast Steel Knife Gate Valve.Its application range is very wide, from coal mining in mines and power plants, slag discharge, slag discharge, to urban sewage treatment; from cement and paper mill slurry transportation to food, sanitation, medicine and other professional pipelines. The ultra-thin design of the Knife Gate Valve completely solves the ordinary gate valve, the slab gate valve, the ball valve, the globe valve, the regulating valve, the butterfly valve and the like with the advantages of small volume, light weight, small flow resistance, no slag accumulation, easy installation and easy disassemble. The flow resistance is large, occupying space, easy to accumulate slag, and difficult to install and maintain. Therefore, a large number of general-purpose cut-off gates and regulating gates are replaced by Knife Gate Valve.We are expecting to become your long term partner in China.
