Model Breakdown
- VM230: SMC Mechanical Valve Series Code
- 02: Port Size Rc1/4
- 30: Actuator Type (Push Button, Mushroom Head)

Working Principle
The VM230-02-30RA employs a poppet structure. When the actuator is operated, the mechanical transmission mechanism drives the valve spool, changing the on/off state of the fluid passage. The valve body features a 3-port design: P port (pressure inlet), A port (working port), and R port (exhaust port). As the valve spool moves to different positions, it switches the fluid flow between P→A or A→R, thereby controlling the action of pneumatic actuators.
Typical Application Scenarios
- Pneumatic Control Systems Used as stop valves and speed control valves for actuators in industrial automation production lines, enabling intermediate stops and inching control to ensure precision and stability in production processes.
- Air-Liquid Circuit Control In air-liquid circuits, employed as drive valves for air motors, blow-off valves, as well as stop valves and residual pressure release valves for air lines, achieving flow distribution and pressure control within the system.
- Packaging Machinery Controls actions like material conveying, sorting, and marking on packaging machines. The mechanical valve enables directional control of pneumatic actuators, ensuring precision and stability in the production process.
- Robotics Serves within robotic pneumatic control systems to control the directional motion of pneumatic actuators, enabling tasks like workpiece gripping, positioning, and placement, enhancing the robot’s motion accuracy and efficiency.
Installation and Usage Precautions
- Installation Requirements The mechanical valve should be installed on a flat, stable base to ensure stable operation. Before installation, verify that the air supply pressure meets the 0~1 MPa requirement and that the air source is clean. During installation, pay attention to the valve’s port direction; the arrow on the valve body should align with the medium flow direction and must not be reversed. Supports various mounting methods: bracket mount, bottom mount, side mount, and panel mount.
- Operating Environment Operating temperature range is -5~60°C. Avoid use in extremely high or low temperatures. Relative humidity should be maintained within an appropriate range to prevent moisture from affecting equipment lifespan. The operating medium should be filtered before use.
- Piping Connections Before piping, thoroughly blow or clean out any cutting dust, cutting oil, and debris inside the pipes. When connecting pipes and fittings via threads, prevent chips from the threaded sections and fragments of sealing tape from entering the piping. If using sealing tape, leave 1.5-2 thread pitches at the end of the male thread bare.
- Regular Maintenance Regularly inspect the valve’s connecting piping and valves to ensure no leaks. Periodically clean the valve surface to keep it clean. Regularly check the valve’s operational performance to ensure long-term stable operation. After prolonged shutdowns, it’s recommended to perform an air purge before restarting.
- Safe Operation Ensure equipment is properly grounded before operation to prevent electric shock risks. Avoid contact with moving parts during operation to prevent pinching injuries. In case of equipment malfunction, stop immediately and have repairs performed by qualified personnel. Depressurize before installation to prevent injury from high-pressure medium ejection. Strictly avoid using the product beyond its rated pressure, temperature, and medium specifications.
