Cartridge Valves - Flow Control Valves - Flow regulator

VSRF-08S

RE18321-32-01(2023-11-07)
Description

A constant flow rate, regardless of system pressures, is established from 1 to 2. The valve cannot be adjusted for variable flow output. Flow from 2 to 1 is limited by the diameter of the selected control orifice and is not pressure compensated. When pressure in 1 meets the setting of relief function, flow is allowed to tank through port 2. Pressure at port 2 is additive to the relief setting of the valve. VSRF-08S is a compact multifunction solution, able to replace in example LS relief and LS flow compensator in one single cartridge.

¹) Only external seals for 10 valves
