Accessory Valves
Pressure Reducing Valve
Pressure Reducing Valve Control pressure to individual devices. For use in double or single acting systems. Direct acting, poppet style, adjustable, cartridge construction. Cartridge may be installed directly into your manifold.
Model 70-5410-10 set the pressure range from 750 to 4500 psi. Repeatability ± 7% Model 70-5410-01 set the pressure range from 150 to 900 psi. Repeatability ± 10% Maximum inlet pressure 5,000 psi. Pressure Reducing Cartridge is interchangeable with the Pressure Limiting Cartridge in the same mounting cavity. Two-port design eliminates need for third fluid line to drain bypass flow (internal leakage) back to system reservoir. n Recommended Filtration: 25 Micron (NOM) /40 Micron (ABS) (minimum). Operation: The Pressure Reducing Valve (PRV) is a Normally Open (N/O) pressure control device. The valve remains open and fluid flows freely to downstream devices (from the valve to devices) until the pressure in the valve reaches the pressure (adjustable) set-point. At the set-point pressure, the valve closes blocking further flow and pressure rise to the downstream devices. If there is a sufficient down stream pressure loss (from the valve to devices), the PRV will re-open, allowing flow to pass through the valve until the pressure again reaches the valve set-point.
