Electric and Pneumatic Control Valves

What is the function of Control Valves?

Whether you're managing single or double-acting actuators, piloting other valves, or controlling airflow SMC's control valves are essential in your industry. Our extensive range provides the best solutions tailored to your specific needs.

Types of Control Valves available at SMC Eesti

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: Use pilot air to control valve position.
• Mechanical Valves and Hand Valves: Adjusted manually by an operator or through interaction with an external object.

Our selection also features safety pressure release valves that are certified according to Machinery Directive 2006/42/EC and meet ISO 13849-1 standards for integration into safety systems.
