M4 series is a compact panel-mounted directional control valve designed for modern pneumatic system integration. The precision anodized body enhances corrosion resistance and supports custom color finish for equipment aesthetics or equipment identification. The integrated side-sealing system eliminates external leakage that eliminates the need for additional adapters, ensuring quick installation and a leak-free seal. With high-quality NBR seals and a low-friction structure, the valve delivers fast response, with 50% longer service life, achieving efficient and stable pneumatic control in space-limited settings.
- Ultra-compact panel-mounted design that saves space while maintaining excellent flow performance
- Precision-ground piston rod (surface roughness Ra ≤ 0.4μm) ensures low friction
- High-sensitivity pilot head with anti-stick coating (μ <0.1) for fast response
- Supports internal or external pilot-operated modes; the double solenoid valve models include a memory function
- Special internal bore coating (3–5μm) provides low actuation force and maintenance-free operation
- Modular structure allows multiple valve combinations for easy system expansion
- Manual override included for convenient installation, commissioning, and system maintenance
This directional control solenoid valve is mainly used in industrial settings with limited installation space and high-frequency pneumatic operation, such as:
- Automated equipment
- Control cabinet integration
- Packaging machinery
- Production lines
