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.

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.

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.

Needle Valve Flow Restictors

Typical application for the NVA is to meter flow, giving speed or full bypass control of a fluid motor.
Typical application for the FCH is to meter flow in one direction while allowing free flow in the opposite direction.
