8533AG RegO DeltaPort® relief valve manifolds are used as the primary pressure relief device on LPG or ammonia storage tanks with threaded connections. The Deltaport incorporates an additional relief valve so that one valve is always out of service. The handwheel allows you to selectively isolate the valve on which maintenance or repair is required without having to empty the tank and keeping the rest of the valves in service. Its RegO "pop-action" relief design ensures maximum protection, with minimal product loss when replacing a relief valve.
