FAQ:

1. Spool Characteristic (B80L)

   The B-spool​ has positive overlap​ (underlap), which provides good centering and dirt tolerance, making it suitable for general industrial applications. The "80L" indicates an 80 L/min rated flow​ with a linear (L) flow characteristic.

2. Control & Feedback (/F1)

   The suffix /F1​ indicates a 4...20 mA current input​ for the command signal. The valve features integrated LVDT position feedback, enabling full closed-loop control of the spool position. It has integrated on-board electronics (OBE), so it does not require an external amplifier.

3. Electrical Connection (K0)

   The /K0​ suffix indicates that the valve is supplied with a plug socket (female)​ but no attached cable or plug. You must procure a separate mating plug (e.g., per DIN 43563 or EN 175201-804) to connect the power and signal wires.

4. Fail-Safe Behavior

   This is a double-solenoid, spring-centered​ valve. In the event of power loss or signal failure (current < 4 mA), the internal springs return the spool to the central (neutral) position​ (typically all ports blocked, depending on the spool symbol).

5. Critical Installation Notes

   • Plug Requirement:​ Unlike valves with pre-attached cables, the /K0 version requires you to wire a separate plug. Ensure correct pin assignment for +24V, 0V, and 4–20 mA signal.

   • Mounting:​ Use the correct ISO 4401-05 (NG10) subplate to ensure proper port alignment and sealing.

   • Cleanliness:​ Maintain oil cleanliness (recommended ISO 4406 19/17/14 or better) to protect the sensitive proportional spool.
