What is a Pneumatic Actuator 3-Way Ball Valve?
A pneumatic actuator 3-way ball valve is an industrial valve type that can control three different flow paths using a pneumatic actuator driven by air pressure. Thanks to its ball valve structure, it changes the direction of the fluid quickly, safely, and with tight sealing. It is widely used for controlling air, gas, oil, and similar fluids.
UNOX pneumatic actuator 3-way ball valves are developed through our company’s R&D studies and are fully domestically produced products with high quality standards.
Working Principle
Pneumatic actuator valves operate by applying pressurized air to the actuator pistons. The actuator rotates the internal ball of the valve by 90° or 120°, changing the flow direction or performing full open/close operation. This enables automatic control without manual intervention.
Pneumatic Actuator Types
UNOX product range includes two different actuator types:
- Single Acting Actuator (USA): Spring-return type; when air supply is cut off, the valve returns to a safe position.
- Double Acting Actuator (UDA): Opening and closing operations are performed using air pressure.
Ball Valve Control Options
Pneumatic actuator 3-way threaded ball valves have two control types:
- Ball Valve On-Off Control: The valve operates in fully open or fully closed position.
- Ball Valve Modulating (Proportional) Control: Flow rate can be adjusted gradually; ideal for precise process applications.
