REGO DUOPORT 8542G

DuoPort® Pressure Relief Valve Manifolds for Small Storage Containers 8542 Series
Model: 8542G, 8542AG, AA8542UA250, AA8542UA265
Xuất xứ: Rego USA

Application:  Designed especially for use as a primary relief device on smaller stationary storage containers, with 2” NPT threaded couplings. These manifolds allow servicing or replacement of either of the two relief valves without evacuating the container or loss of service. The operating lever selectively closes off the entrance port to the relief valve being removed while the remaining valve provides protection for the container and its contents. The rating of each manifold is based on actual flow through the manifold and a single pressure relief valve, taking friction loss into account. It is not merely the rating of the relief valve alone.
Features 
Allows for relief valve removal and replacement on a periodic basis without shutting down and evacuating the container.
• Unique seat ring assemblies provide a smooth tubular section to preclude turbulence and ensure more efficient flow capacity.
• Operating lever is only locked in the mid-position or in a position to seal either relief valve. Placement of the clapper disc in an intermediate position could restrict flow through one of the relief valves, causing it to chatter and destroy the resilient seat disc.
• A rubber plug with chain is provided to protect manifold outlet threads where the relief valve has been removed.
• “Pop-action” design insures maximum protection with only minimal product loss at moderately excessive pressures.
• Resilient relief valve seat disc provides “bubble-tight” seal.
 Relief valves are ASME rated for use with LP-Gas and anhydrous ammonia.
