FAQ

What are the electrical specifications for the included Parker solenoid coils?

The specific voltage (e.g., 12V DC, 24V DC, 110V AC) is indicated on the solenoid coil itself. Please inspect the coil label for the exact electrical requirements before installation.

What is the maximum operating pressure and flow rate for this valve?

While exact specifications for this obsolete model are not readily available, similar Lecq valves of this size are typically rated for pressures up to 350 bar (5000 PSI) and flow rates exceeding 200 L/min. It is recommended to verify compatibility with your system’s requirements.

Can the valve be manually actuated in case of power failure?

Yes, most solenoid valves of this type, including those from Parker, feature a manual override pin or button. This allows for manual shifting of the valve spool for testing or emergency operation when electrical power is unavailable.
