M3 (3/2 way)

Compact 3/2-way mechanical pneumatic control valve with multiple actuator styles, sensitive switching performance, and maintenance-free operation.

Description

The M3 Series Mechanical Control Valve is a compact 3/2-way pneumatic directional control valve designed for manual and mechanically actuated control applications. The series includes roller lever, plunger, push button, selector, and mechanical actuator variants, making it suitable for position sensing, stroke detection, machine sequencing, and pneumatic signal control.

The valve utilizes a sliding-column structure that eliminates back-pressure effects on the actuator force, ensuring smooth and sensitive directional switching regardless of operating pressure. Its sealed internal design provides excellent leak resistance, reliable operation, and long service life in industrial environments.

Constructed with a durable aluminum alloy body and metal control components, the M3 Series offers maintenance-free performance without requiring additional lubrication. Available in port sizes from M5 to 1/4″, these valves are ideal for machine automation, packaging equipment, assembly systems, and pneumatic control circuits.
