How to use, install, and product safety

How to use

Using SMC valves properly depends on the application. This includes the following:

• Pneumatic cylinders: The SMC valve is usually connected to the cylinder. The valve directs air to the cylinder to extend or retract it. The valve buttons can be pressed to manually control the cylinder's movement.
• Pneumatic actuators: The SMC valve controls the airflow to the actuator. The actuator performs a specific task, such as opening a valve or moving a conveyor belt.
• Pneumatic Grippers: The valve controls airflow to the gripper. It allows the gripper to open and close to pick up or release objects.

Installation

• Mounting: The SMC valve can be mounted on a wall or surface using its built-in mounting holes. It has a compact design and can be installed in tight spaces.
• Connections: The SMC valve has air inlet and outlet ports. These ports are connected to the air supply line from the compressor and the lines leading to the cylinders, actuators, or other pneumatic devices.
• Electrical Connections: If the SMC valve is solenoid-operated, it will have electrical connections that need to be wired to the control panel or switches.
• Control Panel: The control panel is mounted close to the valve. It has buttons or levers that control the valve's operation. The buttons or levers may be manual, electric, or sensor-controlled.

Product Safety

• Air Quality: The air used in the SMC valve system should be clean and dry. Moisture and contaminants can damage the valve and other components.
• Pressure Regulation: The SMC valve is rated for specific pressure limits. Ensure the air pressure supplied to the system is within the safe range to prevent the risk of bursting or damaging the valve.
• Avoid Overloading: Do not exceed the maximum load capacity of the cylinders or actuators connected to the SMC valve. Overloading can cause excessive stress and failure of the valve or other components.
• Regular Maintenance: Follow the manufacturer's recommended maintenance schedule. Check for air leaks, unusual sounds, or excessive wear and replace the valve or other components as needed.
