Imported pneumatic three-way ball valve
Introduction Pneumatic three-way ball valve can be divided into type and type. The three-way ball valve is used to switch the flow direction of the medium and can connect two channels that are perpendicular to each other like a flow pattern. Three-way ball valves generally adopt a two-valve seat structure, and can also adopt a four-valve seat structure according to user requirements. The four-seat sealed three-way ball valve has a beautiful appearance, compact and reasonable structure. It can not only switch the flow direction of the medium, but also connect the three channels to each other. At the same time, it can also close any channel to connect the other two channels and flexibly control the pipe. The confluence or divergence of media in the road. The imported pneumatic three-way ball valve adopts a new type of pneumatic actuator, with double-acting and single-acting spring return, rack and pinion transmission, safe and reliable. The large-diameter valve adopts a fork-type transmission pneumatic actuator, with reasonable structure, large output torque, and double Action type and single action type. The working principle of the imported pneumatic ball valve is to make the valve unobstructed or blocked by rotating the valve core. Pneumatic ball valves are light on and off, small in size, can be made into large diameters, have reliable sealing, simple structure and easy maintenance.

Double-acting pneumatic three-way ball valve
The pneumatic three-way ball valve opens the air inlet to exhaust, and pushes the two pistons to separate and move to both sides, and the output shaft Rotate counterclockwise
The pneumatic three-way ball valve closes the air inlet and exhausts, pushes the two pistons together toward the center, and the output shaft rotates clockwise
Single-acting pneumatic three-way ball valve
Pneumatic three-way The ball valve opens the air inlet to exhaust, pushing the two pistons apart to move to both sides, and at the same time compressing the spring, the output shaft rotates counterclockwise
When the pneumatic three-way ball valve is closed and loses air or power, the spring pushes the two pistons to close toward the center Move, the output shaft rotates clockwise
