Re-seal pressure is defined as the downstream pressure at which the check valve closes bubble-tight. Example: For a valve with a spring having a rated cracking pressure of 25 psig (1.72 bar), the actual cracking pressure ranges between 20 and 30 psig (1.38 and 2.07 bar). The re-seal pressure range would be 16 to 20 psig (1.10 to 1.38 bar).

Flow Safe F84L and F88 valves are protecting equipment in food handling, compressor and rotating equipment lubrication systems, and chemical processing, in some cases with highly viscous fluids. Care should be exercised when applying pressure relief valves to systems with viscous fluids, to make sure an adequate relief valve orifice size is chosen.

Pressure relief valves mount between the pump and valve system to protect against overloads. A suitable pilot valve may be used to "vent" the balanced piston relief valve when the system does not require power. This venting unloads the pump through the relief valve at low pressure, avoiding energy waste and reducing operating costs.

The flanged, spring operated pressure relief valve is designed and manufactured as a conventional valve and a balanced bellows valve. The conversion from conventional Series JOS-E or JLTJOS-E in sizes 1" D 2" through 8" T2 10" requires only the addition of a bellows assembly and bellows tail-piece gasket. No other parts are necessary. NOTE
