Smc Pneumatics VM220-N02-34BA 2-way Valve Twist Selector

Product Description

The SMC PNEUMATICS VM220-N02-34BA is a mechanically operated directional control valve designed for pneumatic systems requiring manual flow control. It operates as a 2-way, 2-position valve with a twist selector actuator, giving technicians direct mechanical control over airflow without relying on electrical actuation. The valve features 1/4 inch NPT inlet and outlet ports and carries a Cv rating of 0.870, making it suitable for moderate-flow compressed air circuits. The black body construction suits industrial panel and manifold installations. Pneumatic system integrators, maintenance technicians, and automation specialists are the primary installers of this type of valve.

This valve is used in industrial pneumatic control circuits where a simple on/off or open/close flow path is needed. The twist selector actuator allows operators or technicians to manually switch between two positions, making it well suited for machine lockout points, manual bypass lines, and selector stations on pneumatic panels. Applications span light manufacturing, process control, and equipment maintenance scenarios where electrical solenoid actuation is not required or not practical. The 1/4 inch NPT porting fits standard compressed air plumbing found across most industrial facilities.

Key Features

• 2-way, 2-position valve configuration for straightforward open/close pneumatic control
• Twist selector actuator provides tactile, manual position switching without tools
• 1/4 inch NPT inlet and outlet ports for direct connection to standard compressed air lines
• Cv rating of 0.870 supports moderate compressed air flow rates
• Black body finish suits industrial panel and cabinet installations
• No electrical actuation required, reducing wiring complexity in manual control stations

Compatibility

Designed as an OEM-style replacement or drop-in addition for pneumatic control systems requiring a 2-way, 2-position mechanically operated valve with 1/4 inch NPT porting.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician. Depressurize and lock out the compressed air supply before removing any existing valve or fittings. Use appropriate thread sealant rated for compressed air on the NPT connections and verify the twist selector moves freely through both positions before returning the system to service. Follow applicable local codes and the equipment manufacturer guidelines for pneumatic component installation.
