First, Q911F3 three-piece thread electric ball valve overview
The Q911F3 three-piece threaded electric ball valve is suitable for two-way cutting and adjustment applications. The connection between the valve and the actuator is directly connected. The electric actuator has a built-in servo system. It does not need to be equipped with a servo amplifier. It can be controlled by inputting 4-20mA signal and 220VAC power supply. The utility model has the advantages of simple connection, compact structure, small size, light weight, small resistance, stable and reliable operation and the like.

Third, Q911F3 three-piece thread electric ball valve features
1. The fluid resistance is small, and its resistance coefficient is equal to the pipe length of the same length.
2. The structure is simple, small in size and light in weight.
3. It is close and reliable. At present, the sealing surface material of the ball valve is widely used in plastic and has good sealing performance. It has also been widely used in vacuum systems.
4. The operation is convenient, the opening and closing is rapid, and the rotation is 90° from full opening to full closing, which is convenient for long-distance control.
5. The maintenance is convenient, the ball valve has a simple structure, and the sealing ring is generally movable, and the disassembly and replacement are relatively convenient.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium does not cause erosion of the sealing surface of the valve.
7. Wide range of applications, from small to a few millimeters, up to a few meters, from high vacuum to high pressure
