Rubber Check Valve
Product Introduction
A check valve made of wear-resistant materials
Opening Pressure
0.001Mdda
Product Improvement
Rubber check valve of Yantai Group is made of Yantai Group 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.
♦ Adavantages
Yantai wear rubber with wear resistance, corrosion resistance and high flexibility, the 0.25 mm Yantai 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.
Rubber check valve of Yantai Group can be customized in specs, size, color, etc. according to customers’ requirements.
Rubber check valve of Yantai Group adopts flange or pipe strap connection.
Excellent resistance to frost, more suitable for cold areas
♦ Product Description
One side of Yantai 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.
♦ Work Principle
Rubber check valve of Yantai Group 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.
♦ Application
Rubber check valve of Yantai Group 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.
