SMC VM100 Series Mechanical Valve, R 1/8 Port Size, Zinc Die Cast Alloy Body Material - VM131-01-01SA

This mechanical valve provides directional control for pneumatic systems, operating as a 3/2-way valve with mechanical actuation. Designed for air and inert gases, it offers a compact side-port configuration with a roller lever actuator and mechanical spring return, suitable for installations requiring a small, robust control valve in industrial automation and machinery environments.

Features and Benefits:

• 144L/min flow rate enabling efficient actuator cycling
• Operates up to 1MPa for high-pressure pneumatic circuits
• Mechanical spring return ensures reliable reset after actuation
• Roller lever actuation allows simple mechanical triggering
• R1/8 pneumatic connections for common industrial tubing
• Withstands temperatures from -5°C to +60°C for varied conditions

Applications

• Suitable for small pneumatic cylinders and actuators
• Ideal for machine tool air control panels
• Used with pick-and-place automation fixtures
• Can be used for safety interlocks requiring mechanical actuation
• Suitable for valve manifolds in compact assemblies

What materials are used in the valve body and why does that matter?

The body is zinc die-cast alloy which provides rigidity and dimensional stability while keeping weight low, helping resist mechanical stress in typical factory environments.

Which thread standards are available for connection compatibility?

Threads are supplied to Rc and NPT standards, allowing direct connection to imperial and BSPP-style fittings without adaptors on the R1/8 ports.

How is the actuator supplied and are visual indicators available?

The unit uses a hard steel roller lever actuator and can be fitted with control buttons in red, black, yellow or green where visual identification of control points is required.

What is the valve’s normal position and exhaust behaviour?

In the resting state the valve exhausts the downstream port

actuation delivers supply to the output while the spring returns the spool on release.
