High-flow proportional control valve with center-block function, featuring brass alloy body with electroless nickel plating for corrosion resistance. The dual-coil design enables precise mid-position control in pneumatic circuits. Integrated surge suppression protects against voltage spikes. Requires 5μm filtered dry air with oil mist (ISO 8573-1 Class 3.4.3).
- Automated clamping systems with position hold requirements
- Plastic injection molding machine core-pull mechanisms
- CNC tool changer actuator control
- Automotive assembly line balancing cylinders
- Food processing equipment with cleanroom compatibility
Installation protocol:
Mount horizontally with pilot exhaust ports downward. Lubricate seals with ISO VG32 turbine oil before initial use.
Allow 15mm clearance for manual override access. Perform monthly exhaust port blow-down maintenance.
