These duckbill check valves are a cost effective way to control back pressures from sewage treatment plants, outfalls and tidal operations. They are low maintenance, fully passive flow devices which do not require external power or manual assistance to operate.
All Proco check valves are manufactured completely with a top quality barnacle and algae resistant rubber. They will not freeze or deform and function solely on the inlet and back pressures which will be present in each application. Details of the flanged and slip-on check valves can be found on our products page.
US-based Proco Products Inc. has over 30 years’ experience in this market and prides itself on being a global provider of a wide range of expansion joints and check valves.
