Pressure Reducing Valve

Metric Accessory Valves

• Use this valve in double or single acting systems.
• Direct acting, poppet style, adjustable, cartridge construction.
• Cartridge construction is the adjustable, direct acting, poppet style.
• Model 47-0540-01 set the pressure range from 52 bar (5.2 MPa) to 310 bar (31 MPa). Repeatability ± 7%.
• Model 47-0540-03 set the pressure range from 10 bar (1 MPa) to 62 bar (6.2 MPa). Repeatability ± 10%.
• Maximum inlet pressure is 350 bar (35 MPa).
• Two-port design eliminates the need for third fluid line to drain bypass flow (internal leakage) back to the system reservoir.
• Recommended Filtration is 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 downstream 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.
