Specifications:
The rubber flap check valve has a complete 100% flow area, low head loss and resistance to clogging. To ensure long-term reliability, because the valve's reinforced rubber floppy disk is the only moving part, its integral O-ring provides a drop-proof seal under low and high working pressures.
The rubber flap check valve has a unique and simple design with only one moving part. The flap does not swing from the hinge pin; it just flexes open. The seat is at a 45° angle. The baffle moves 35° from opening to closing, usually before column reversal occurs. It has non-slam characteristics. The valve does not require regular maintenance. At the same time, the combination of 45-degree seat angle, short stroke and the inherent memory of its flexible disc can provide quick closing and anti-impact operation. Recommended for water, sewage, gas, oil and rubber lining chemicals.
