The water hammer arrestor is meant to prevent against damage and destruction of the pipeline or other devices caused by hydraulic shock waves because of the valve quickly closed quick closure of the valve. It is therefore applicable to the outlet of pump discharge check valve, inlet of pipe outlet valve or facet in order to absorb backflow impact and water flow shock. This arrestor does not require repairs at all after it is installed and while it is in use. The only moving part is the O-ring sealed free piston. All parts and components released from the factory have gone through tests and their reliability is proven to exceed that required for the normal scope of use. They can adapt to any commercial or domestic pipe pressure. 

PPP water hammer arrestor

Installation: A standard pipe T-joint may be used to install the water hammer arrestor in the new or old pipe system. 

Maintenance: Maintenance free. The piston is the only moving part. 

Fluid temp range: -4.4°C~+100°C 

Operating pressure: Normal 35~500P.S.I.G. 

The transient maximum pulse pressure is 2000P.S.I.G. at the thread end and 750P.S.I.G. at the flange end.
