The CMN310 Series is a high-performance NAMUR-interface solenoid valve engineered specifically for process control automation. Designed in full compliance with the VDI/VDE 3845 (NAMUR) mounting standard, this valve mounts directly onto quarter-turn pneumatic actuators (butterfly valves, ball valves, etc.) without any external tubing. This direct-mount design eliminates potential leak points, ensuring a compact, safe, and highly reliable valve automation solution.

Product Description

High Flow Capacity & Low Pressure Drop – Optimized internal flow passages ensure rapid actuator response, meeting the demands of high-cycle operations and large-bore valve controls.
Extended Service Life & Robustness – Constructed with high-strength aluminum alloy (stainless steel optional) and precision spool-seal technology, the valve is cycle-tested to over millions of operations, significantly lowering maintenance frequency.
Manual Override (Standard) – Equipped with a push-button (or pull-type) manual override for convenient on-site commissioning, testing, and emergency position control during power outages, enhancing operational ease.
Wide Operating Range – Suitable for a broad pressure range, with optional high/low-temperature seals available to withstand harsh industrial environments (-20℃～+60℃ and beyond)
