Hydraulic Flow Control Valves

hydraulic flow control valves
 

Depend on our flow control valves to give just the right flow — constantly.

We offer flow and pressure capabilities of 15-340 l/min [4-90 US gal/min] and up to 450 bar [6,500 psi], respectively.

Circuit Examples

 

Needle Valves

Needle Valves Example Schematic
Needle Valves Example Schematic
  • Fully adjustable, non-compensated flow control.
  • Non-compensated manual flow control for an actuator or for bleeding oil from the circuit.
  • Available with integral free reverse flow check.
  • Flow range: 10-380 l/min [3-100 US gal/min].
  • Pressure capability up to 315 bar [4,500 psi].

 

Restrictive Flow Control Pressure-Compensated

  • Two-ported design for a constant flow rate, regardless of load pressure changes.
  • Commonly used for meter-in or meter-out circuits to control actuator speeds, for example in load-lowering applications.
  • Bi-directional version available, allowing compensation in both flow directions.
  • Flow range: 15-190 l/min [4-50 US gal/min].
  • Pressure capability up to 315 bar [4,500 psi].

 

Bypass Flow Control Pressure-Compensated

  • Three-ported design for a constant flow rate to the priority port, regardless of load pressure changes. Remaining flow is directed to the third port.
  • Commonly used to direct fixed flow to a priority function or circuit, while making secondary flow available to other intermittent functions or the tank.
  • Flow range: 23-100 l/min [6-26 US gal/min].
  • Pressure capability up to 315 bar [4,500 psi].

 

Flow Divider/Combiners

Flow Divider/Combiners Example Schematic
  • Pressure compensated valves that combine and divide flow at a predetermined ratio.
  • Commonly used for combining (forward) and dividing (reverse) flow to hydraulic wheel motors or synchronizing cylinder motion.
  • Flow range: 45-340 l/min [23-90 US gal/min].
  • Pressure capability up to 450 bar [6,500 psi].

 

Velocity Fuses

  • Designed to allow free flow in both directions. If flow exceeds the ‘trip point’ in one direction (lowering), the valve shifts to stop or greatly reduce the flow.
  • Commonly used for lifting/lowering single-acting cylinders where the load is required to stop/slow down in the event of a hose failure.
  • Flow range: 30-110 l/min [8-29 US gal/min].
  • Pressure capability up to 210 bar [3,000 psi].
