Rubber Check Valve

Rubber Check Valve

A check valve made of wear-resistant materials
【 Capacity 】:
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 solutions; 48 hours later, the performance of the rubber has no obvious change, so the applicable range is very wide.


Xinhai wear rubber with wear resistance, corrosion resistance and high flexibility, the 0.25 mm Xinhai rubber strip stretches to out of shape until 800% length; the rubber prolongs the service life of the check valve 2 times. 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

【Product Structure】

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.

Rubber Check Valve-case

In Sudan gold processing plant, the customer chose Xinhai rubber check valve, according to the actual circumstance of plant, Xinhai technical personnel adopted special flange connection, it has good sealing and corrosion resistance in operating process, and it can operated normally in harsh environments. Experimental data show that Xinhai NO.35 rubber flexible check valve can operating in 90˚C high temperature and soaked in 30% concentration sulfuric acid solution for 48 hours.
