    摘要: In various implementations, an electronic actuator may be coupled to a valve to provide the ability to shut off anhydrous ammonia flow through the valve (e.g., in emergencies). The valve may be coupled to anhydrous ammonia tanks, such as nurse tanks and/or storage tanks. The electronic actuator may include a handle and a bracket. The handle and the bracket may include at least two attractive components that are magnetically attracted to each other upon application of an electric current and the valve may be open. When the electric current is cut, the attractive components of the handle and the bracket may not be magnetically attracted to each other and the valve may be shut off. A controller (e.g., a switch) may be coupled to the electronic actuator to allow control of the electric signal to the electronic actuator.
