Compact Motion Control Valves - Flow Control Valves - Flow divider and combiner

DRF (G 3/8)

RE18309-55-01(2023-10-30)
Description

This valve gives division of input flow from V to C1-C2, and re-combines flows in reverse direction from C1-C2 to V. The ratio between the flows through C1 and through C2 is maintained constant (typically 50% / 50%) over a wide range of pressure variations and of pressure imbalance in order to synchronize the motion of 2 actuators in both forward and reverse directions. In flow division mode, should either C1 or C2 be blocked, approximately 1÷2% of the available flow can be forced through the port still open.

General:
Operating pressure:
  • up to 210 bar (3000 psi)
Flow division ratio: 50% - 50%For any chosen inlet flow capacity (refer to table Z), the slippage, or the difference from theoretical value between the divided flows, depends from the inlet flow, and is lowest in the top portion of the selected range: generally it never exceeds ± 3%.:
Weight:
  • 0.9 kg (1.98 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.
  • Aluminium
Fluid:
  • Mineral oil (HL, HLP) according DIN 51524
Fluid temperature range:
