The 8542 RegO DuoPort® relief valve manifolds are used as the primary pressure relief device on LPG or ammonia storage tanks with threaded connections. The Deltaport is made up of two valves; one in working position and an additional relief valve so that there is always one valve out of service. The handwheel allows you to selectively isolate the valve that requires maintenance or repair without having to empty the tank and keeping another valve in service. Its RegO "pop-action" relief design ensures maximum protection, with minimal product loss when replacing a relief valve.
