What is this valve?
It is a pilot-operated proportional pressure reducing valve with integrated electronics. It reduces a higher inlet pressure (P/B) to a precisely controlled lower outlet pressure (A) based on an electrical command signal.
What are its key features?
Proportional Control: Output pressure is proportional to the 4–20 mA input signal.
Integrated Electronics (OBE): The amplifier is built into the solenoid, simplifying wiring.
High Capacity: NG20 size handles flows up to ~200 L/min at 315 bar.
Safety: Includes maximum pressure limitation to protect against overcurrent faults.
How does it work?
The electrical signal (4–20 mA) controls the pilot solenoid, which regulates the pressure in the main valve's control chamber. This sets the reduced pressure at port A. If the signal is lost, the valve closes, and pressure at A drops (depending on load).
Where is it typically used?
Used in hydraulic systems requiring precise, variable pressure control, such as clamping circuits, press controls, or secondary circuit pressure regulation in industrial machinery.
How do I wire it?
Power: 24V DC to the coil connector.
Signal: Connect the 4–20 mA command signal to the designated pins on the integrated electronics connector (K31 type).
Drain: Port Y must be connected directly to tank with minimal backpressure.
What if the pressure is unstable?
Check for contamination in the pilot orifice.
Verify the 4–20 mA signal is stable and the drain line (Y) is not blocked.
Ensure the inlet pressure is sufficiently higher than the desired reduced pressure.
