Alternative name: electric shut-off valve for ammonia, electric shut-off valve for liquid ammonia, electric shut-off valve for ammonia
Model: BAQ941F-25/40C BAQ941F-25/40P
Overview of electric shut-off valve for ammonia:
The electric ammonia shut-off valve is a 90 ° rotating cut-off O-type floating ball valve with excellent sealing performance, large flow capacity, small flow resistance coefficient, simple structure, easy maintenance, long service life, equal valve body channel and connecting pipe diameter, and several media can flow without loss. The explosion-proof actuator with manual device is usually used in places with strict sealing requirements. In addition to controlling gas, liquid and steam media, it is also suitable for controlling sewage and media containing fibrous impurities. It is widely used in petroleum, chemical industry, metallurgy, light industry, paper making, power station, refrigeration and other work fields.

Features of ammonia electric shut-off valve:
1. The fluid resistance is small. The ball valve has the smallest fluid resistance among all kinds of valves. Even the reduced diameter ball valve has relatively small fluid resistance.
2. The thrust bearing reduces the friction torque of the valve rod, and the valve rod can be used for long-term operation and balance flexibly.
3. The sealing performance of the valve seat is good. The sealing ring made of PTFE and other materials is easy to seal, and the sealing capacity of the ball valve increases with the pressure of the medium.
4. The valve stem seal is reliable. Since the valve stem only rotates rather than moves up and down, the packing seal of the valve stem is not easy to be damaged, and the sealing capacity increases with the increase of medium pressure.
5. Due to the good self-lubricating property of polytetrafluoroethylene material, the friction loss with the ball is small, and the service life of the ball valve is long.
6. The lower mounted valve stem and the convex step of the valve stem head prevent the valve stem from ejecting. If the valve stem seal is damaged due to fire, metal contact can also be formed between the convex step and the valve body to ensure the valve stem sealing.

The electric shut-off valve is applicable to the process occasions and fluid control systems where the pipeline pressure difference is large and the sealing requirements are strict, and the pipeline medium is cut off. Electric shut-off valve is a kind of pipeline pressure electronic component for industrial automation process control. Electric shut-off valve is usually used for remote switching or regulating control of pipeline medium. Electric shut-off valves mainly include electric liquid ammonia shut-off valve, electric ammonia shut-off valve, electric ammonia shut-off valve, electric liquid ammonia ball valve, ammonia electric ball valve, ammonia electric ball valve and other series. The electric actuator adopts an integrated structure, with a built-in servo system. It does not need to be equipped with another servo amplifier. It can control the operation by inputting 4-20mA control signal or 1-5VDC and 220VAC power supplies. The electric valve has the advantages of small size, portability, reliable performance, simple matching, large flow capacity, etc. The electric control valve can be used in situations where the working temperature is - 29 ℃ to+150 ℃ and the working pressure is PN16-PN40MPa.
