Smc Pneumatics VM220-N02-05A 2-way Valve Straight Plunger

Product Description

The SMC PNEUMATICS VM220-N02-05A is a mechanically operated pneumatic valve designed for directional flow control in compressed air and fluid power systems. It operates as a 2-way, 2-position valve, meaning it either opens or closes the flow path based on mechanical actuation. The straight plunger actuator engages when depressed by a cam, trip dog, or mechanical stop, making this valve well suited for position-sensing and machine sequencing applications. The valve carries a Cv rating of 0.870, indicating the volume of flow it passes at a given pressure differential. Both the inlet and outlet ports are 1/4 inch NPT, which fits directly into standard pneumatic manifolds and plumbing fittings without adapters.

This valve is used in industrial automation, machine tool, and material handling applications where a physical mechanical trigger is needed to control a pneumatic circuit. It is typically installed at the end of a travel stroke, at a fixture point, or at a machine guard position to signal or control downstream actuators. The 2-position design provides a simple open or closed function, making it straightforward to integrate into ladder logic or hard-wired pneumatic circuits. Licensed pneumatic system integrators, automation technicians, and industrial maintenance professionals are the primary installers of this type of component.

Key Features

• 2-way, 2-position valve configuration provides simple open or closed flow control
• Straight plunger actuator suitable for use with cams, trip dogs, and mechanical stops
• Cv rating of 0.870 supports typical low-to-medium flow pneumatic circuit requirements
• 1/4 inch NPT inlet and outlet ports for direct connection to standard pneumatic fittings
• 2-port design simplifies circuit integration in sequential and position-sensing pneumatic systems

Compatibility

Designed as an OEM-style mechanically operated valve for use in industrial pneumatic control circuits requiring a 2-way, 2-position straight plunger actuator with 1/4 inch NPT porting.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or industrial automation professional. Depressurize and lock out the pneumatic supply before removing or installing any valve in the circuit. Ensure NPT threads are wrapped with thread sealant tape and tightened to fitting manufacturer specifications to prevent leaks. Verify that the mechanical actuating element, such as a cam or trip dog, aligns correctly with the plunger travel to achieve full actuation without side-loading the plunger.
