TOP VALVE Back Pressure Valves & Pressure Relief Valves
Back Pressure Valves and Pressure Relief Valves named Top Valve. A new line of diaphragm style, has been introduced by Primary Fluid Systems Inc. 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.
Note: CRN is available on certain valves. Please contact factory for price and availability.
•• For pressure relief plastic body valves add 0.25" to dimensions
Note: Dimensions are the same for standard back pressure and pressure relief valves except as indicated above.
Flow capacity through TOP VALVE Back Pressure Valves/anti-siphon and Pressure Relief Valves under continuous flow conditions @ 50 PSIG with ambient temperature water.
