Duckbill Check Valves
Onyx Duckbill rubber check valves efficiently ensure the mono-directional flow of water, slurries, sewerage and sludge. The valve consists of an elastomeric "duckbill" which, with the chosen connection, provides a simple rugged design with no mechanical parts that would be prone to wear and jam in conventional valves.
The Slip-on Check Valve is fixed by slipping over a pipe and securing with stainless steel clamp bands available in 304 or 316. The Flanged Check Valve has a flanged connector and a galvanised carbon steel back-up flange with stainless steel options.
The Inline Check Valve is a simple reliable cost effective method of back flow prevention that is designed to be installed between two mating flanges.
