Product description
The pneumatic three-way ball valve is composed of a pneumatic actuator connected to a three-way ball valve. The three-way ball valve can be divided into T-type and L-type. The fixed pneumatic ball valve can be equipped with valve positioner input control signal (4-20mADC or 1-5VDC) air source to control the operation. It can also be equipped with stroke limit switch, solenoid valve, triple piece and 0.4-0.7MPa air source to realize switch operation. It is widely used in petroleum, chemical, electric power, metallurgy, medicine, food, textile, paper, shipbuilding, environmental protection and other industrial sectors to realize the diversion of various media.
Product design features
