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.
•t
Remote sensing can eliminate problems caused when an inlet
pressure drop to the SRV exceeds 3 percent.
•t
Retrofit kits easily and economically convert an existing
Consolidated 1900 SRV to the new 2900 POSRV design.
•t
Replacing and/or upgrading the existing population of safety relief
valves with the 2900 series valve eliminates costly piping changes.
Features and Benefits
•t
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:
•t
The Dirty Service option ensures operation in dirty, precipitating
and viscous fluids.
•t
Bonnet is now standard for all pilot valves.
•t
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.
•t
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.
•t
Pilot Gag
This prevents the pilot-operated relief valve from opening while
equipment is being subjected to an operational hydrostatic test.
•t
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.
•t
The 2900 pilot valve enables enhanced performance with a variety
of solutions.
•t
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.
