EPDM Rubber Duckbill Check Valve 8 Inch CS SS304 Duck Bill Valve
Product Description
8Inch Weather Resistance Rubber EPDM Flange Duckbill Check Valve
The Rubber Duckbill check valve consists of elastic neoprene rubber and man-made fiber, manufactured through special processing. Its shape resembles a duckbill, hence the name. With no internal pressure, the duckbill remains closed due to elastic force. As internal pressure increases, the exit gradually opens, allowing high-flow-rate liquid discharge.
