Eco Valve has released a new line of back pressure valves and pressure relief valves which are ideal for metering pump/chemical dosing applications. They are designed for long life and ease of installation and maintenance with a 3 year warranty. Available in PVC, CPVC, PVDF, polypropylene and 316L stainless steel, they are designed to be used as a two port off line pressure relief valve to help protect the discharge side of positive displacement pumps from system failure due to over pressure caused by a blockage or accidental valve closure on the downstream side of the pump. New features include a completely adjustable pressure range of 7-150 PSIG and a built-in air release to reduce priming difficulties with metering pumps. The valves are available in sizes, ¼ in to 4 in and are available in 10 configurations: threaded, socket, union and flanged. No moving parts in wetted chamber provides superior choice for dirty fluid applications.
