In the rapidly changing world of hydraulics, Magnet Schultz of America (MSA) utilizes its marketplace knowledge and proven engineering and manufacturing expertise to provide full-service Hydraulic Actuators for both mobile and industrial applications. Our various reference designs can be tailored to precisely meet your system’s performance requirements.
Hydraulic Solenoid Actuators (Tubes, Coils and Assemblies)
MSA offers three Hydraulic Solenoid Actuator reference design sizes. Because most applications require unique performance characteristics, we custom engineer each Actuator Tube and/or Coil to exactly meet your application’s requirements.
A Hydraulic Actuator Assembly includes a tube, coil, coil retention nut and an o-ring. Each Assembly’s specifications directly correlate with those of the individual components.
MSA’s Hydraulic Actuator Coils are over-molded, utilizing high temperature nylon (HTN), PPS or Rynite thermo-plastic materials. These Coils offer water and dust ingression ratings of IP65, IP67 and IP69 (depending on the individual coil size and design).
MSA is a recognized leader in the design and manufacture of high-quality, high-performance Electrohydraulic Actuator Tubes. Our Hydraulic Tubes are custom engineered to meet the specific force, stroke, hysteresis, and other performance criteria.
Bi-Directional Hydraulic Actuators
MSA offers two different Bi-Directional Hydraulic Actuator technologies—a linear motor and the push-pull hydraulic actuator—either of which can be engineered to meet customer specific application requirements.
- Linear Motor – recently patented, single coil, bi-directional design
- Push-Pull Hydraulic Actuator Tube – conventional dual coil, dual-length
When paired with MSA’s Hydraulic Actuator Coils, these revolutionary, high-performance, Bi-Directional Actuator Tubes can be tailored to precisely meet the challenges of your application.
MSA’s Linear Motor Hydraulic Actuator offers bi-directional operation in the same physical length as our conventional, 19mm and 22mm diameter proportional reference design tubes.
The stroke of the Linear Motor, in the push or pull direction, is half the total stroke of the conventional, single-direction tube designs.
The Linear Motor is perfectly suited to applications that require more instantaneous actuation, because it can provide a faster actuation speed than the single-direction tube.
The Push-Pull Hydraulic Actuator Tube is twice the length of our single direction Tubes. This dual length, integrated package can provide equivalent force and stroke in either the push or the pull direction.
MSA’s conventional Push-Pull Hydraulic Actuator Tubes are available in three diameters—19mm, 22mm and 31mm—in proportional or on/off configurations.
HAZ-LOC® (Hazardous Location) Electrohydraulic Solenoid Coils
Engineered for safety critical markets, this family of Electrohydraulic Coils is designed, tested and certified for worldwide use in hazardous and volatile location environments—including gas and dust atmospheres present in petroleum exploration and production, chemical processing, and facilities involving the transfer and storage of grain or other dry materials.
The HAZ-LOC coil family is designed to be mounted on any manufacturer’s hydraulic valve which utilizes actuator pressure tube diameters of 13mm, 16mm, 19mm and/or 22mm. Standard voltages are 12 and 24 VDC, and 120 and 240 VAC. An internal bridge rectifier enables the use of AC voltage(s). An integrated junction box provides ease of electrical connection, while maintaining explosion proof characteristics. All HAZ-LOC coils are rated IP66, NEMA 4X for water and dust ingression.
Operating below 135 degrees C (T4 rating), HAZ-LOC offers explosion proof capability meeting NEC 500, NEC 505, CEC/CSA, ATEX and IECEx certifications and ratings.
MSA’s collaborative innovation approach is perfectly suited to design and achieve certification for customized derivatives of the original HAZ-LOC coil family, enabling the resulting new coil to interface with customer specific actuator tube diameters and valve configurations. The product family is also adaptable to non-hydraulic valve applications.
SPOOL LOCK® Solenoids
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.
