A line of diaphragm style back pressure and pressure relief valves has been introduced by Primary Fluid Systems Inc.called Top Valve.
Features include a completely adjustable pressure range of 0-150 PSIG and a built-in air release to reduce priming difficulties with metering pumps.
Top Valve back pressure valves and pressure relief valves are available in seven sizes, 1/4" through 2" NPT and eight (8) materials of wetted construction. The seat design of this new line of valves greatly extends the normal life expectancy of the diaphragm.
