Commonly used with high volume blowers compressors and air powered conveyors these valves quickly relieve a large amount of air in systems with a pipe size of 2 or greater. The operating principle of this volume tank is similar with an accumulator on hydraulic. Typically these systems should be checked at the same time the safety instrumented system sis is proof tested. Facilities to isolate the volume tank from the air supply and bleed the air upstream of the check valves are also required not only to check that the system works initially but also for future proof testing.
