The main purpose of the electric motor shut-off valve shut-off valve flanged connections for nominal pressure valve PN1.6 ~ 16MPa valve, pipeline operating temperature of the oil, chemical, pharmaceutical, fertilizer, power industry, etc. -29 ~ 550 ℃ various working conditions , cut off or connected piping media. Driving a manual mode, gear, electric, pneumatic. Electric shut-off valve advantages 1, simple structure, manufacture and maintenance more convenient. 2, the working stroke is small, open and close a short time. 3, sealing, and the sealing surface friction force is small, longer life expectancy. Overview of electric power shut-off valve shut-off valve and flange valve belong to the same type of ball valve principle, the electric actuator or pneumatic actuator and shut-off valve of two parts, the difference between its closure member is a ball valve how much body centerline for rotation around the body to achieve open, and close a valve. Valve in the pipeline is mainly used for cutting, distribution and change the direction of media flow. Two-piece ball valve, three-valve, is a new valve has been widely used in recent years.
