Functions of Control Valves
SMC's electric and pneumatic control valves play a crucial role in your application, whether you're managing single or double-acting actuators, piloting other valves, or controlling airflow. Our extensive range provides optimal solutions tailored to your specific needs.
Types of Directional Control Valves available at SMC
Directional control valves regulate the flow of fluids such as oil, water, steam, or air in hydraulic and pneumatic systems. They can be categorized based on their actuation mechanism:
- Electric Valves: Operated by electrical signals, including both direct and pilot-operated solenoid valves.
- Pneumatic Valves: Control valve position using pilot air.
- Mechanical and Manual Valves: Position is adjusted manually by an operator or an external object interacting with the valve.
Our portfolio includes safety pressure release valves certified under Machinery Directive 2006/42/EC, suitable for safety systems as per ISO 13849-1 standards.
