Cartridge Valves - Flow Control Valves - Flow regulator

VRFA-12A-TF

RE18321-14-01(2023-11-07)
Description

A constant flow rate, regardless of system pressures, is established from 1 to 2 while a minimum pressure differential of 14 bar (200 psi) exists between the two ports. 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.

1) Only external seals for 10 valves
