Functions of Directional Control Valves
SMC's directional control valves are essential for various applications, whether you're managing single or double-acting actuators, piloting other valves, or controlling airflow. Our diverse range ensures the best solutions tailored to your needs.
SMC's types of Control Valves
Directional control valves manage fluid flow in hydraulic and pneumatic systems, handling substances like oil, water, steam, or air. They can be classified based on their actuation method:
- Electric Valves: Operated by electrical signals, including direct and pilot-operated solenoid valves.
- Pneumatic Valves: Use pilot air to control valve position.
- Mechanical and Manual Valves: Adjusted manually by an operator or external object.
Our selection includes safety pressure release valves, certified under Machinery Directive 2006/42/EC and compliant with ISO 13849-1 for use in safety systems.
