Emerson introduces new pilot operated relief valve

Tanks and Terminals,
Emerson has introduced a new pilot operated relief valve for installation on pressurised bullet tanks used to store liquid propane and anhydrous ammonia.
This type of pressure relief valve (PRV) is typically installed on tanks fabricated by original equipment manufacturers (OEMs), who provide them to end users, engineering firms or contractor customers. The new valve is certified under UL132 and American Society of Mechanical Engineers (ASME) Section VIII.
With a pre-installed national pipe tapered (NPT) thread standard 2 in. male hex nipple, this new product serves the need for a solution with a 2 in. connection that provides the same benefit as traditional multi-ported valves, but with simplified installation and maintenance. For this application, the PRV must be connected directly to the tank, with no isolation valve between the tank and the PRV. This National Fire Protection Association (NFPA) 58 code requirement presented challenges when testing the PRV while the tank was pressurised and in operation.
The new relief valve addresses this issue because it was designed specifically for this type of service. Operation is implemented with a dual pilot array, providing redundancy, and allowing for removal of one pilot for testing while the other is operational.
