Technical parameters and characteristics
Rubber Flap Check Valve
The rubber Flap check valve is mainly composed of the valve body, valve cover and valve flap. The rubber flap is made of steel plate as the pressure-bearing part and reinforced nylon cloth as the substrate. The outer layer is made of heat-vulcanized overall rubber coating technology. The valve flap is flexible in opening and closing. free of jamming, and has a long service life. The valve adopts a streamlined design, with the characteristics of small head loss, not easy to accumulate debris, simple maintenance, etc.
