Q644/Q645Pneumatic three-way ball valve
1、 Pneumatic three-way ball valveProduct Overview
Pneumatic three-way ball valve produced by Tingyang CompanyIt is a three channel rotary ball valve,Used for medium diversion, merging, and flow direction switching, any pipeline can be used as an inlet or outlet. Pneumatic three-way ball valves are divided into two types: pneumatic three-way L-shaped ball valves and pneumatic three-way T-shaped ball valves, which can meet different production process requirements. Pneumatic three-way valveLType ball valve is a pneumatic three-way valve that cuts off two of the three pipelinesTThe type ball valve realizes the merging and splitting of three connected pipelines. Pneumatic three-way ball valve matched with electrical valve positioner, input4～20mADCSignal and0.4～0.7MPaThe gas source can be used to control the operation and adjust parameters such as pressure, flow rate, temperature, and liquid level. Also equipped with travel limit switches, solenoid valves, pressure reducing valves, and0.4-0.7MPaThe gas source can achieve switch operation and send two pairs of passive contact signals to indicate the opening and closing of the valve. Pneumatic three-way ball valves are widely used in industrial fields such as chemical, petroleum, textile, power, food and pharmaceutical, refrigeration, aviation, aerospace, papermaking, etc.
2、 Pneumatic three-way ball valveProduct Features
（1）The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.
（2）Simple structure, small size, and light weight.
（3）Tight and reliable, plastic is widely used as the sealing surface material for ball valves with good sealing performance, and it has also been widely used in vacuum systems.
（4）Easy to operate, quick opening and closing, from fully open to fully closed, just rotate90°Easy to control from a distance.
（5）Easy to maintain, ball valve structure is simple, and the sealing ring is generally movable, making disassembly and replacement relatively convenient.
（6）When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the sealing surface of the pneumatic three-way ball valve.
（7）Widely applicable, with diameters ranging from a few millimeters to several meters, suitable for applications from high vacuum to high pressure.
