Rubber flap swing check valve

The seal ring of rubber disc check valve is designed as lean to shorten the closing time and reduce the pressure caused by water hammer. Valve disc is made of acrylonitrile-butadiene rubber and steel plate by pressing under high temperature. The advantages of check valve include wash-out resistance, reliable seal, simple structure and convenient utilization. Rubber disc check valve, consisting of body, bonnet,disc and spring, is mainly used at the exit of pipe in petroleum, chemical engineering and other industries.

Product Introduction

The rubber disc swing check valve is mainly composed of three main parts, the valve body.the valve cover and the rubber valve. The rubber flap is made of steel plate, steel bar andreinforced nylon cloth, and the outer layer is made of rubber, and the valve switch life canreach 1 million times. The valve is designed with full flow area, which has the characteristicsof small head loss, no accumulation of debris and qradual maintenance and so on. Thevalve is mainly applied to the water supply and drainage system, which can be installed atthe outlet of the pump to prevent the reverse flow and water hammer from damage to thepump. The valve can also be installed on the bypass pipe of the water intake pipe toprevent water from flowing back.
