Application Guide

Flow Safe, Inc., based in Orchard Park, NY is proud to introduce and bring to the world market the "Next Generation" of 'Enhanced Performance' Direct Spring and 'High Performance' Pilot Operated Safety Relief Valves. Our valves are designed by engineers with over 52 years of experience in Safety Relief Valve technology. They offer tighter lift tolerance, lower blowdown, improved mechanical integrity and superior capacities (allowing the use of a smaller 'more cost effective' valve) when compared with the more conventional safety relief valves currently available. Flow Safe customers buy smaller valves, save money!
