Flow Divider FDB 20

Flow Divider FDB-20 Hydraulic Valve

Features

  • Up to 450 bar (6 527 PSI)
  • Up to 150 L/min (39.6 GPM)
  • Direct in-line mounting.
  • Threaded connections to ISO 1179 (BSPP/Gas), ISO 11926 (UNF).

Operation

The bidirectionnal flow divider controls the speed between wheels of the same axle or between different axles by dividing or combining the flow.

The flow divider is equipped with an electric or hydraulic controlled by-pass and can be used in open or closed loop circuits.

Operation

Hydraulic symbol

HP valve, 3 solenoid valves and electric by-pass

Operation

HP valve and hydraulic by-pass

Operation

P: High pressure
A and B: Outlet
T: Drain
G1: Preferential charge pressure
G2: Plugged charge pressure
Pil: Hydraulic control
