2600M - Multimedia Valve
2600M Series Certified Design for Multi-Media
The 2600M Series multi-media service relief valves provide inventory flexibility and superior performance in two-phase flows. With this option, the same relief valve can be set on one media and have both air/vapor and liquid capacities stamped on the nameplate without set point adjustments, as allowed by ASME Code Case 2787.
This allows customers to simplify their install base by ordering one valve that can be used in multiple medias. ASME Code Case 2787 allows multiple marking of nameplate capacities for pressure relief valves. Manufacturers or assemblers with UV designation may place more than one certified capacity on the valve nameplate provided the valve has been certified for each media with no adjustments and within tolerance requirements in Section XIII.
The type number is differentiated from the existing 2600 Series design by adding the appropriate Special Construction designator as referenced in the Type Numbering System. Add the "M" designator for all API sizes, and "P" for former API 2 1/2" flange sizes. Example: 26DA10M-120.
This option is available for all conventional, BalanSeal, or O-ring seat 2600 series valves with orifice sizes D through U.
