A check valve made of wear-resistant materials
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
Relying on external pressure to close valve, clean closure, good
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
One side of Xinhai rubber check valve is round or square tubular,
connected with flange or pipe clamp; the other side is flat like
fishtail with an autistic duckbilled one-way valve in the middle
which is produced through reducing surface. This makes positive
circulation resistance minimum and makes reverse reliable and no
sealing with the help of rubber elasticity.
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
Xinhai rubber check valve is widely used in coast, beach, marina,
reservoir, municipal drainage, sewage pond emissions, odor barrier,
and pump system. It can completely eliminate sundries, and has a
maximum capacity of pipeline flow.
