Product features

The utility model solves the problems of four kinds of complex valve operation, such as the valve flow direction, high cost and so on. The pneumatic four-way ball valve is an X-shaped vertical channel. Its characteristics are that the two channels of the ball are arranged in X-shape, and the diameters of the four channels are all distributed on the equatorial circular section of the ball. When the ball rotates 90 clockwise, the two opposite channels can be interconnected.

Features of pneumatic four-way ball valve:
 
The pneumatic four-way ball valve can realize the positive and negative water supply switching, and the water supply mode can be switched once every 90 degrees. It is called bidirectional water supply rotary valve in power station system and air reversing switch valve in petrochemical system. It is suitable for circulation system of liquid, gas, dust, slurry and solid particle medium, such as forward and reverse circulation water supply system of unit cooler in power station.
Reversing principle of pneumatic four-way ball valve:
 
 
"Ll '" type four-way ball valve only needs to operate the wrench or actuator to rotate the ball 90 ° and switch the flow direction of the two kinds of media at the same time, which is convenient and rapid, and can realize the effect of multi-purpose of one valve.
