Description
The S3 Series Control Valve is a compact 3/2-way pneumatic mechanical control valve designed for manual, mechanical, and position-actuated control applications. The series includes multiple actuator styles such as roller lever, plunger, push button, selector, foot-operated, and manual control configurations, providing flexibility for a wide range of industrial automation systems.
Designed with a direct-acting shutoff structure, the S3 Series offers excellent sealing performance, fast response, and reliable directional switching. External force actuation models can be used for position sensing, limit switching, and machine sequence control, while manual variants allow convenient operator control in pneumatic circuits.
The valve body is manufactured from durable aluminum alloy, with metal actuator components that provide long service life and stable operation. The lubrication-free design reduces maintenance requirements while supporting reliable performance in industrial environments. Available in port sizes from M5 to 1/4″, the S3 Series is ideal for machine automation, pneumatic control panels, packaging equipment, and motion control systems.
