SKU: SV-M4 Category:

The M4 Series is a high-performance 5/2-way solenoid valve strictly adhering to the NAMUR mounting standard. This series is the industrial benchmark for controlling double-acting pneumatic actuators. By mounting directly onto the actuator face, it creates a seamless, “pipe-free” connection that reduces potential leak points and simplifies system architecture.

Designed for high-frequency automation, the M4 series features a precision-ground piston rod and specialized sealing technology that ensures reliable switching over millions of cycles. The valve body is hard-anodized for superior wear resistance. With an IP65 protection rating and CE certification, it is the ideal choice for process industries, water treatment, and chemical plant automation.
