Discription
Product Overview
The Pneumatic Three-Way Ball Valve consists of a pneumatic actuator combined with a three-way ball valve structure. The valve is available in both T-port and L-port configurations, enabling flow diversion, mixing, and directional switching in industrial pipeline systems.
The valve can be equipped with a valve positioner to receive control signals such as 4–20 mA DC or 1–5 V DC for automated operation. Optional accessories including limit switches, solenoid valves, air filter regulators, and 0.4–0.7 MPa pneumatic air supply systems are available to achieve automatic on/off control.
Widely used in petroleum, chemical processing, power generation, metallurgy, pharmaceutical, food processing, textile, paper manufacturing, marine, and environmental protection industries, the valve is suitable for controlling and diverting various industrial media.
