BS5153 Standard Ductile Iron Metal Sealing Swing Check Valve For Water Pipeline Use
Product introduction:
The H44H series metal sealing check valve is mainly suitable for horizontal installation in water supply and drainage systems. It can be installed at the outlet of the water pump to prevent backflow and water hammer damage to the pump, it can also be installed on the bypass pipe of the inlet and outlet pipes of the reservoir to prevent water from flowing back into the water supply system.
Check valves are generally suitable for clean medium and are not suitable for the mediums containing solid particles and high viscosity. The check valve is installed at the outlet of the water pump for shut-off and check purposes. It is an ideal equipment to eliminate the damage of water hammer to the water pump unit and pipeline network. When there is a sudden power outage, the valve can automatically close to protect the safety of the water pump and pipeline.
