Control Valve

Control Valve – Category Overview
Control valves are the core product line of our automation control systems portfolio. We integrate Ball, Butterfly, Gate, and Globe Valves with Pneumatic/Electric Actuators, Positioners, Solenoid Valves, and Limit Switches to provide complete fluid control solutions for our customers.

Unlike manual valves, control valves are defined by precision control and reliable execution. From flow path design, actuator torque matching, to control accessory selection and integration, everything is completed in-house to ensure system response accuracy and long-term stability.
