Use
Ammonia water regulating valve is a regulating element that uses ammonia as the control medium. It is widely used in scheduled refrigeration, ammonia process flow, ammonia vaporization, and other occasions to control and adjust parameters such as ammonia flow rate, pressure, and temperature, in order to achieve stable process control and optimized production efficiency.

Structure
1. Valves mainly consist of valve body, valve seat, valve stem, valve core, valve cover, etc.
2. The flow characteristics of the valve are equal percentage, straight line, and equipped with electric or pneumatic actuators.
Install
1. The door should be installed vertically on a horizontal pipeline.
2. It is necessary to install according to the medium flow direction indicated by the arrow.
3. During installation, ensure that the opening and closing positions of the electric actuator are consistent with the opening and closing positions of the valve window.
