High-flow proportional control valve with dual-coil latching design, featuring anti-vibration structure and zero-pressure differential activation. The aluminum alloy body with hard anodizing treatment ensures durability in humid environments. Requires 5μm filtration with automatic drain function for optimal performance.
- Plastic injection molding machine sequence control
- Automated assembly line clamping systems
- CNC machine tool coolant flow regulation
- Lithium battery production vacuum handling
- Food packaging gas flush systems
Installation protocol:
Mount horizontally with coil upright. Maintain minimum 15mm clearance
between valves in manifold arrangements. Use copper-free lubricants
during maintenance. Pre-charge pilot circuit before full-pressure operation.
Critical note:
Not compatible with phosphate ester fluids. Maximum allowable
pulse frequency: 5Hz. Always install downstream moisture separator.
