Abstract: In various implementations, a manual actuator may be coupled to a valve to provide the ability to shut off anhydrous ammonia flow through the valve remotely (e.g., in emergencies). The valve may be coupled to anhydrous ammonia tanks, such as nurse tanks and/or storage tanks. The manual actuator may include manual release member, a breakaway member, a handle, and pull cord(s). The handle may allow a coupled valve to be opened and/or closed. The handle may allow the valve to be shut off at the valve, in some implementations. The pull cord(s) may allow a coupled valve to be remotely closed.

Abstract: 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.
