MECHANICAL AND COMBINED MECHANICAL/ELECTRONIC ACTUATOR FOR ANHYDROUS AMMONIA EMERGENCY SHUT OFF VALVES

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...

Beschreibung
Zusammenfassung:	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.
