The Consolidated Type 2900 Series Pilot-Operated Safety Relief Valves. The 2900 Series Safety Relief Valves is a mix of Consolidated type 1900 and type 3900.
Features
Closed bonnet for spring protection
A pilot gag prevents the pilot-operated relief valve from opening while equipment is undergoing operational hydrostatic testing
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
Pop action and modulating pilots allow for application versatility
Pilot seat design allows for self-cleaning operation and is tolerant to icing and dirty conditions
Remote actuation and sensing can eliminate problems caused when then inlet pressure drop exceeds 3 percent
The metal seat option incorporates proven technology from the 1900 series safety relief valve seat design
Retrofit kits easily and economically convert an existing
Consolidated 1900 SRV to the 2900 POSRV design
Replacing and/or upgrading existing API 526 spring-loaded safety relief valves with the 2900 series valve eliminates costly piping changes
Process temperatures that range from -400°F (-240°C) to 1200°F (649°C) can be met using the heat exchanger option
The dirty service option ensures operation in dirty, precipitating and viscous fluids.
