7 MPa Valves
Pressure Reducing Valve
Pressure Reducing Valve for Circuit Pressure Control For use in double or single acting systems. Direct acting, poppet style, adjustable, cartridge construction. Cartridge can be installed directly into your manifold. Set Range from 1 MPa (10 bar) to 6.2 MPa (62 bar) recommended.
Repeatability is +/- 10% of set pressure. Maximum inlet pressure 20 MPa (200 bar). 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) (min.) 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 PRV is designed for use in both single acting and double acting systems.
For proper sealing, the mating surface must be flat within 0.08 mm with a maximum surface roughness of 1.6 µm R a NOTE: Maximum system flow rate is 5.7 l/m, unless otherwise noted. Excess flow voids warranty. Pressure Reducing Valve (PRV) Model No. L7-0512-00 Description Assembly Set Pressure Range 1.0 MPa (10 bar) to 6.2 MPa (62 bar) System Pressure 20 MPa (200 bar) ILML70500
