Xinhai rubber check valve opens by inner pressure difference and closes by outer pressure. When in the forward work the tiny water pressure can open the valve and the pressure is greater the valve opening is larger. In the reverse working the valve naturally closes.
Xinhai rubber check valve is made of Xinhai 35 wear – resistant rubber with strong wear and corrosive resistance. Experiment shows that it be immersed in a concentration of 30 sulfuric acid or alkaline Processs 48 hours later the performance of the rubber has no obvious change so the applicable range is very wide.
The opening is very easy because of the high elasticity of the rubber. 1 kilograms of fluid can easily open the valve without blockage.
Relying on external pressure to close valve clean closure good sealing.
Under general conditions the head loss can be reduced minimum.
Xinhai rubber check valve can be customized in specs size color etc. according to customers’ requirements.
Xinhai rubber check valve adopts flange or pipe strap connection.
Excellent resistance to frost more suitable for cold areas.
