Characteristics of pneumatic three way ball valve

May 11, 2021

Three way ball valve is divided into single acting and double acting according to the acting type. The characteristic of single acting type is that once the power source fails, the ball valve will be in the state required by the control system.

There are two types of pneumatic three-way ball valve, one is T-type, and the other is L-type. T-type pneumatic ball valve can make three orthogonal pipelines connect with each other and cut off the third day channel, playing the role of diversion and confluence. L-type pneumatic three-way ball valve can only connect two mutually orthogonal pipelines, which can not keep the pipeline unblocked for the third day. It only does the distribution function. These two kinds of pneumatic three-way ball valves have long service life, large flow capacity and small resistance.

The closing part of the ball valve is a ball. The ball rotates around the center line of the valve body to open and close the valve. Ball valve is mainly used to cut off, distribute and change the flow direction of medium in pipeline. Ball valve is a new type of valve widely used in recent years. It has the following advantages:

1. The fluid resistance is small, and its resistance coefficient is equal to that of the same length of pipe.

4. Easy operation, quick opening and closing, from full open to full close as long as 90 °， It is convenient for remote control.

5. Easy maintenance, simple structure of ball valve, movable sealing ring, easy disassembly and replacement.

6. When the valve is fully opened or closed, the sealing surface of the ball and valve seat is isolated from the medium, and the medium will not cause the erosion of the valve sealing surface.

The pneumatic three-way ball valve is developed on the basis of pneumatic ball valve, which is responsible for the regulation of the applicable working conditions. The structural characteristics of this pneumatic ball valve are detailed as follows:

Characteristics of three way ball valve

1. Three way ball valve is divided into T-type and L-type, with long service life, large flow capacity and small resistance

2. Three way ball valve is divided into single acting and double acting according to the acting type. The characteristic of single acting type is that once the power source fails, the ball valve will be in the state required by the control system

3. The three-way ball valve adopts the integrated structure, the sealing type of 4-face seat, less flange connection, high reliability and lightweight design.
