Compact Motion Control Valves - Flow Control Valves - Flow regulator

VRFC3-VU (G 3/4)

RE18309-44-01(2023-10-27)
Description

A constant flow rate, regardless of system pressures, is established from E to R, while a minimum pressure differential of appr. 5 bar (70 psi) exists between the two ports. Input flow supplied to E in excess of the regulated output at R is by-passed to T. Output flow can be varied from closed to the nominal maximum rating for the valve. Reverse flow from R to E is limited by the selected opening of the restrictor and is not pressure compensated. Flow from T to E or from T to R is not possible. Increasing or decreasing inlet flow may cause slight increase or decrease of Regulated flow.

General:
Operating pressure:
  • up to 210 bar (3000 psi)
QE= max. inlet flow “E” port 150 l/min. (40 gpm):
QR= max. regulated flow “R” port 90 l/min. (24 gpm):
Flow range adjustment:
  • 0 - 3 turns
Weight:
  • 2.4 kg (5.3 lbs)
Manifold material:
  • Note: Note: aluminium bodies are often strong enough for operating pressures exceeding 210 bar (3000 psi), depending from the fatigue life expected in the specific application. If in doubt, consult our Service Network.
