Detailed introduction

One Way Non Return Swing Check Valve

* Rubber disc check valve is mainly composed of body, cover and rubber disc three parts.Rubber disc is made by steel plate, steel bar and the reinforced nylon fabric substrate.This valve is usually installed in the outlet of the pump or inlet of water pool to prevent the water backflow and avoid damages to the pump caused by the water hammer phenomenon.

* The water flow in water supply or irritation networks often starts or stops abruptly causing hydraulic hammer shock, the main factor for breakage and damages of the pumps and pipes. The check valve with the rubber blocking eliminates the pump and network destruction risks because it receives and absorbs all the created high pressure functioning like the shock absorber of an automobile. The rubber disc check valve is designed to provide the best possible protection to pump installations and water networks.
