Pressure Reducing Valve

Accessory Valves

• 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 inlet pressure <3000 psi, 150 to 900 psi outlet pressure, >3000 psi, 300-900 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.
• 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.

The graph shows the repeat range based on set pressure.
