4DP / 4DEP – Hydraulic Pilot, CETOP 7 & 8
The Spica 4DP and 4DEP series are heavy-duty, pilot-operated directional control valves designed for high-flow hydraulic systems. These valves act as the primary control element for large cylinders or motors, using a two-stage design to handle high pressures and flow rates that would be too great for a direct-acting solenoid.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
