Accessory Valves
Pressure Reducing Valve
Pressure Reducing Valve 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. n 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.
