We are proud to be the factory authorized representative for Primary Fluid Systems, Milton Roy, Griffco and many others. We offer their extensive catalogs of Valves including those listed below.

We now offer Back Pressure Valves and Pressure Relief Valves/Safety named TOP VALVE. This is a new line of diaphragm style valves. New 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.
