Flow Controls

External Pilot Flow Restrictors

Typical application for the QP-RIP is in combination with a proportional pressure reducing valve on the piloting line. Flow will increase proportionally to the pressure supplied from the proportional valve.

product details

  • Pilot operated flow restrictor.
  • 276 Bar (4000 PSI) max pressure.
  • 60-120 LPM (16-32 GPM) max oil flow
  • 2.5-22 Bar (35-315 PSI) Pilot pressure range
  • Max internal leakage 35cc/min @250 Bar

Flow Divider/Combiner Valves

Typical application for the FDA, FDB, and FDH is to synchronize two independent cylinders or hydraulic motors in both directions. Typical application for the FDT is to provide positive traction for vehicle transmissions. If one leg loses load, the valve insures flow to the other leg.

product details

  • 240 Bar (3500 PSI) Max oil pressure.
  • Sizes available up to 115 LPM (30 GPM) Max inlet oil flow.
  • Up to +/- 4% accuracy of flow splits of max input flow.
  • Industry standard cavities.
  • -40 – 120 C (-40-250F) operating temperature range.
