SMC Push Button (Mushroom) Mechanical Valve VM100 Series, R R 1/8, III B

This mechanical valve is a compact, manually actuated pneumatic directional control device intended for air and inert gas systems. It provides a two-position, three-port function with side piping and a push mushroom control for straightforward manual operation. The valve is suited to installations requiring a small footprint and side-mounted connection, and operates across typical industrial temperature ranges.

• R 1/8 ports deliver BSPP compatibility for common fittings
• 144 L/min flow enables efficient medium-duty pneumatic circuits
• Mechanical spring return ensures defined neutral position
• Push button mushroom gives clear manual actuation feedback
• Operates up to +60°C for warmer ambient applications

• Suitable for valve islands and local manual overrides
• Ideal for pneumatic tooling requiring compact side porting
• Used with jigs and fixtures needing quick manual control
• Can be used for maintenance isolation in production lines
• Appropriate for test rigs handling inert gas supplies

Both pneumatic input and exhaust use R 1/8 threaded ports compatible with BSPP fittings.

In its normal state the valve exhausts the working port while the spring returns the spool to the default position.

The valve functions up to a maximum operating pressure of 1.0 MPa and can operate down to -100 kPa under applicable conditions.

Manual push actuation via a black mushroom button couples with a mechanical spring return for position resetting.
