SPOOL LOCK Solenoids block the movement of the spool in a hydraulic valve. MSA offers a reference design that can be tailored to fit your application.
Increased user safety and system reliability are important benefits of MSA’s SPOOL LOCK Solenoids. Specifically designed to meet the rigors of hydraulic applications, this Solenoid includes an over-molded coil and wire-lead grommet (providing IP65 water and dust ingression protection), and a corrosion resistant spring and external plating.
A SPOOL LOCK Solenoid is mounted on a hydraulic valve where it can encounter a special groove in the valve’s spool. When the SPOOL LOCK coil is energized, the plunger pulls-in, allowing free movement of the spool. When de-energized, the spring inside the SPOOL LOCK Solenoid moves the plunger into the spool groove, blocking the movement of the spool.
The SPOOL LOCK Solenoid is a fail-safe device—if electrical power is removed from the coil (by one of multiple sensors that are mounted throughout a piece of equipment), the plunger will immediately move to lock the valve.
Customizable design features of MSA’s SPOOL LOCK Solenoid reference design include:
- Coil voltage
- Mounting threads
- Length of lead wires and type of connector
SPOOL LOCK Solenoids are commonly used on skid steer-style construction equipment, fork-lifts and aerial man-lift work platforms. In any application, the presence of a SPOOL LOCK Solenoid, coupled with the proper design and use of the equipment, will help prevent unintended movement of hydraulic valves and the system components they operate.
In customer applications where the performance, mounting, or other uniquely demanding requirements cannot be met by modifying MSA’s SPOOL LOCK Solenoid reference design, Magnet-Schultz of America can provide a fully custom design.
