Imported electric three-piece ball valve(Q911F, Q911H) is assembled by the left and right valve housing and the middle valve body. Four long bolts are threaded through the three-section housing, and the middle body is clamped tightly from both ends. The biggest advantage of the electric three-piece ball valve is that it is particularly easy to disassemble. When a valve fails or needs maintenance, the four bolts can be removed directly to remove the middle part of the valve body without removing the pipe threads. It not only reduces the probability of failure, but also improves operational efficiency. It is especially suitable for working conditions with small mechanical volume and narrow space.
Principle of imported electric three-piece ball valve (Q911F, Q911H):
The three-piece motorized ball valve offers reliable sealing performance and high pressure. The principle of action is to drive the spool to rotate 90 degrees through the power supply voltage of the electric actuator, which opens and cuts off the medium. It can be designed as a two-position switch to control the medium, and it can also adjust the proportion of the medium flow, pressure, temperature and other parameters in the pipeline.

Classification and difference of imported electric three-piece ball valve (Q911F, Q911H):
The electric one-piece ball valve is one-piece and the ball is held in place by a plug for easy maintenance and can be used in applications that require quick opening and closing.
The electric two-piece ball valve consists of two parts, and the two balls are clamped and fixed. Maintenance is relatively complex. The tightness of the intermediate screw is related to whether it will leak or not.
An electric three-piece ball valve is similar to a two-piece ball valve. It consists of the left and right end caps and the middle valve body, which is then clamped by the neck flanges on both sides. Its pressure is higher than that of the other two types.
