4M Series NAMUR Standard 5/2 Way Solenoid Valve | Actuator Mounted Plate Type Valve

Brand: SOLH by Richge Technology

1. Product Overview

     The SOLH 4M series is a professional NAMUR standard 5/2 way plate-type solenoid valve specially designed for pneumatic actuator automatic control. It strictly complies with international NAMUR side mounting standards with standard mounting holes on the valve bottom. The valve can be directly laminated and installed on the side of pneumatic ball valves and butterfly valve actuators without intermediate adapter air pipes. Exclusively used for valve automatic control circuits, it fully matches the Airtac 4M series standards and is structurally different from conventional 4V tube-type solenoid valves.

4. NAMUR Mounting Core Advantages & Key Selection Points

     • Integrated NAMUR Base Air Port: The bottom of the valve is embedded with A/B air ports. After fitting with the actuator, it automatically docks with the two air inlet holes of the actuator. No external air pipes are required for A/B ports; only P air inlet and R1/R2 exhaust ports need external air source connection, simplifying piping structure and reducing leakage points.

     • Built-in Manual Test Push Rod: Equipped with a manual debugging button on the valve side, supporting manual valve opening and closing test after power off, convenient for on-site installation, debugging and equipment maintenance.

     • Dual Control Mode Characteristics: 4M×20 double electric control models adopt power-off self-locking memory structure to maintain the current valve position; 4M×10 single electric control models automatically reset by spring force after power off, meeting safety reset and positioning holding demands respectively.

     • Compatible Manifold Mounting: Shares the same base specification as 4V series (4M100M/200M/300M manifold base). It supports centralized air supply for multiple valves via manifold installation and can also be directly mounted on a single actuator for independent operation.

6. Typical Matching Applications

     • Valve Automatic Control System: 4M210-08 matched with DA/SR pneumatic actuator + ball/butterfly valve, widely used in petrochemical, water treatment and pipeline fluid switching equipment.

     • Valve Island Integrated System: Adopt 4M200M multi-link manifold base to realize centralized air supply and integrated installation of multiple 4M series solenoid valves for automated pipeline clusters.

     • Pipeline Piping Matching: Connect external thread ports with KQ2 quick-connect male thread straight fittings to quickly dock with the main air source pipeline for stable and leak-free connection.

One Sentence Summary

     The SOLH 4M series is a dedicated NAMUR standard plate-type 5/2 way solenoid valve for pneumatic actuators, featuring tubeless direct mounting, lubrication-free operation and IP65 protection, being the optimal supporting control component for automatic switching of pneumatic ball valves and butterfly valves.
