Emerson has introduced the Fisher 63EGLP-16 Pilot Operated Relief Valve for installation on pressurized 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), that 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-inch male hex nipple, this new product serves the need for a solution with a 2-inch connection that provides the same benefit as traditional multi-ported valves, but with simplified installation and maintenance.

The Fisher 63EGLP Pilot Operated Relief Valve addresses this and other issues because it is the only pilot-operated relief valve on the market 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.
