SOLH 4M series plate-type 5/2-way solenoid valves strictly comply with international NAMUR mounting standards, purpose-built for direct assembly onto pneumatic actuators driving ball valves and butterfly valves. The integrated bottom base comes with pre-embedded P, A, B, R1 and R2 air passages, enabling seamless docking with actuator air cavities without external tubing for A/B working ports. This streamlined layout drastically cuts pipeline layout workload and potential air leakage points compared with conventional tube-connected 4V series solenoid valves. This lineup adopts internal pilot spool construction with oil-free operation, offered in single-coil spring reset (4M×10) and double-coil latching memory (4M×20) configurations covering three size grades: 4M100, mainstream 4M200 and high-flow 4M300. Single electric control variants automatically reset under spring tension once power is disconnected for fail-safe reset scenarios, while double electric control versions retain their switching position steadily after power cut to sustain valve opening/closing status for long-term pipeline locking. Each unit is fitted with a side-mounted manual override button for convenient offline commissioning and maintenance testing. Coils support widely used global AC/DC voltages with IP65 dustproof and waterproof ingress protection, suitable for rigorous working conditions in water treatment, chemical pipelines and general industrial fluid switching. The series is dimensionally compatible with manifold bases shared with the equivalent 4V series, supporting standalone actuator installation or centralized valve island assembly via multi-station manifolds. With certified standard NAMUR interface, interchangeable with mainstream Airtac 4M series, it serves as a dedicated matched control component for automated on-off regulation of pneumatic ball and butterfly valve actuators.
