Advantages of the Parker D3FP Series Proportional Directional Control Valve
-
Extremely high dynamics: D3FP attains frequency-response comparable to servo valves, enabling rapid and accurate control.
-
High flow & pressure capacity: Capable of handling substantial flow while maintaining stable operation under high pressure.
-
Defined spool position at power-down: On power loss, the spool returns to a predefined safe position (e.g. neutral or defined P/T configuration), enhancing safety and control reliability.
-
Onboard electronics & flexible control signals: Supports common input signals (e.g. +/-10 V), simplifying integration with PLCs or control systems.
-
Standard mounting & fluid compatibility: Built per ISO 4401 / DIN 24340 / CETOP RP121 (NFPA D05) — easy to integrate in standard hydraulic circuits; compatible with hydraulic oils per DIN 51524 / 535 and also water-glycol fluids in certain seal versions.
-
Compact yet robust design: Weighing about 6.5 kg, the D3FP balances compactness with durability, suitable for industrial environments.
