Description

Design Features:

The rubber flap check valve is mainly composed of three main parts: the valve body, the valve cover and the rubber flap. The rubber flap is made of steel plate, steel rod and reinforced nylon cloth as the substrate, and the outer layer is covered with rubber. The valve flap has a life of up to 1 million times. The valve adopts a full flow area design, which has the characteristics of small head loss, not easy to accumulate debris, and easy maintenance. This valve is mainly used in water supply and drainage systems and can be installed at the outlet of the water pump to prevent backflow and water hammer from damaging the pump. The valve can also be installed on the bypass pipe of the water inlet and outlet pipes of the reservoir to prevent the pool water from flowing back into the water supply system.


ZG Check Valve Features: 

1. Rational Structures, Reliable Sealing.The product structure is reasonable, the seal is reliable, and the performance is good.

2. Hard-alloy Seal, Long Life.The sealing surface is welded with hard alloy, which has good wear resistance and long service life.


Field of Application:

Size Range: 2“-24”/DN50-DN600

Working Temperature: ≤80°C

Allowable Operating Pressure: PN10/PN16/125LB/150LB

Check Valve for use inpetrochemical industry, Chemical,Fiber Textiles, plastic, paper making, power industry, steel, rubber and gas systems.
