Smc Pneumatics VM120-N01-34RA 2-way Valve Twist Selector

Product Description

The SMC PNEUMATICS VM120-N01-34RA is a 2-way, 2-position mechanically operated valve designed for manual flow control in pneumatic systems. It uses a twist selector actuator for direct, tactile actuation without the need for electrical input. The valve features a 1/8 inch NPT inlet and carries a Cv rating of 0.110, making it suitable for low-flow pneumatic circuits. It is installed by pneumatic technicians and maintenance professionals working on compressed air systems in light industrial and manufacturing environments.

This valve fits into pneumatic control circuits where a compact, manually actuated shutoff or diverter is required. The twist selector design allows the operator to lock the valve into one of two positions, providing positive flow confirmation without relying on electrical solenoids or pilot air. Typical applications include machine tool pneumatics, small actuator control, and panel-mounted manual overrides in automated equipment.

Key Features

• 2-way, 2-position valve configuration for straightforward on/off or open/closed flow control
• Twist selector actuator provides positive manual positioning without electrical input
• 1/8 inch NPT inlet for compatibility with standard compressed air plumbing
• Cv rating of 0.110 suited for low-flow pneumatic circuits
• Red actuator color aids visual identification of valve state in panel or machine installations
• 2-port design supports direct inline installation

Compatibility

Designed as an OEM-style replacement or direct addition for pneumatic control systems requiring a 1/8 inch NPT, 2-way, 2-position mechanically operated valve with a twist selector actuator.

Installation Notes

Installation should be performed by a qualified pneumatic technician. Depressurize the air supply line completely before removing or installing any valve component. Apply thread sealant appropriate for pneumatic service to NPT threads and avoid overtightening, which can crack the valve body. Verify that system operating pressure does not exceed the valve's rated limits as specified by the manufacturer.
