Typical Application Scenarios

This valve is not meant for high-power drive circuits, but rather for signal and pilot control:

• Pilot Control of Large Valves: Used to provide the pilot pressure for large proportional or servo-operated directional valves (like the D41 or D91 series).

• Clamping Pressure Control: Ideal for managing low-force hydraulic clamping or braking systems where pressure must be adjusted dynamically.

• Test Benches: Used in laboratories or test rigs to simulate varying pressure conditions at low flow rates.

• Tension Control: Regulating the pressure on hydraulic clutches or brakes in paper and textile winding machinery.

Important Precautions (Usage Notes)

• Pilot-Only Flow: Remember that the maximum flow is only 10 L/min. Attempting to use this valve as a primary pressure regulator for a high-flow actuator will result in a massive pressure drop and potential system failure.

• Barometric Feedback: The D1FV series often utilizes barometric feedback to ensure stable pressure control regardless of temperature changes. Ensure the vent/drain ports are not obstructed.

• Filtration Requirements: Because the internal parts are precision-machined for low hysteresis, the oil must be kept clean. Maintain a minimum cleanliness of ISO 4406 18/16/13.

• Solenoid Orientation: While the mounting position is unrestricted, it is generally recommended to mount the valve with the solenoid horizontal to prevent air pockets from affecting the proportional response.

• Seal Compatibility: Since this model features FPM (Viton) seals, it is compatible with a wider range of fluids including some phosphate esters, but always verify compatibility with your specific hydraulic fluid type.
