电动三通法兰球阀
Electric three-way ball valve, composed of electronic electric actuator and three-way ball valve, is a rotary cut-off regulating valve with advantages of tight closure, compact structure, light weight and easy maintenance. It is widely used in automation and control of pipeline for gas, liquid, steam, oil and other corrosive media.
1. The integrated structure and four-sided valve seat sealing mode are adopted for the three-way ball valve, which ensures high reliability and achieves light weight design;
2. Three-way ball valve is divided into T-type and L-type, and it has such advantages as long service life, large flow capacity and small resistance;
3. The two-sided valve seat is applied for ball valve of three-way four-sided valve seat type with L-type flow channel to ensure balanced stress and reliable sealing at closed channel. The ball valve is mainly used for flow reversal;
4. The four-sided valve seat is applied for ball valve of three-way four-sided valve seat type with T-type flow channel to ensure balanced stress and reliable sealing at closed channel. The ball valve is mainly used for flow dispersing, mixing and reversal as well as complete opening of the three channels.
