Consolidated* 2900 MPV Series Pilot-Operated Safety Relief Valve Overview The 2900 series pilot-operated safety relief valve is another innovative Consolidated product line offering from GE, a world leader in pressure relief valve technology. The 2900 series valve is a blend of GE's Consolidated type 1900 safety relief valve and GE's Consolidated type 3900 pilot-operated safety relief valve. These GE products have a proven track record for performance, versatility and ease of maintenance. Remote sensing can eliminate problems caused when an inlet pressure drop to the SRV exceeds 3 percent. Retrofit kits easily and economically convert an existing Consolidated 1900 SRV to the new 2900 POSRV design. Replacing and/or upgrading the existing population of safety relief valves with the 2900 series valve eliminates costly piping changes. Process temperatures that range from -450°F (-267 .8°C) to 1200°F (648 .9°C) can be met by using the heat exchanger option.. GE's Consolidated pilot valve has a unique design that combines top performance, capabilities and features within an economical, modular assembly. This is based on the successful design of an optimized safety “system” that offers versatility of application, yet provides cost-effective standardization. Here are the key characteristics of the 2900 series valve: The Dirty Service option ensures operation in dirty, precipitating and viscous fluids. Bonnet is now standard for all pilot valves. 39MV22 [751 - 3750 psig (51 .78 - 258 .55 barg)] The 39MV22 modulator, which replaces the 39MV37, is built internally into the pilot valve. This design reduces product cost, improves modulating performance and increases energized seal life. 39MV72 [3751 - 6250 psig (258 .62 - 430 .92 barg)] Based on the same design as the 39MV22, this pilot allows the Consolidated product line to expand into the 2500# class pressure range. Pilot Gag This prevents the pilot-operated relief valve from opening while equipment is being subjected to an operational hydrostatic test. 2900 series POSRV Backflow Preventer. When the 2900 pilot-operated relief valve initially was released, a backflow preventer was required for high back pressure conditions. During additional testing, it was discovered that a backflow preventer is not required for non-bellows valves equipped with a standard piston O-ring. Valves equipped with a Teflon® energized seal still will require a backflow preventer. The 2900 pilot valve enables enhanced performance with a variety of solutions. Through its improved seat tightness to 98 percent of set pressure, and adjustable blowdown to 2 percent of set pressure, the 2900 series valve allows higher system pressures that can increase the yield of the process. fact sheet

fact sheet Conventional Type Main Valve Double Seal Soft Seat The double seal design incorporates the merits of both a soft seat and a metal seat design valve. The 45° metal seat provides the load bearing surface to transmit piston pressure force, while the slotted O-ring retainer allows the O-ring to be pressurized and accomplish the primary sealing function. How the Double Seal Works Two unique features distinguish the Consolidated O-ring seat seal safety valve from other designs. These are the 45° metal-to-metal load-bearing seats and the slotted O-ring retainer. Double Seal GE's O-ring seat...
