Type 13900 Series pilot-operated safety relief valves meet ASME Section VIII criteria, balancing simple build and exceptional flow performance. Built with a small fail-safe pilot and high-capacity main valve that allows up to 200 square inches of orifice area, this model reduces the quantity of valves required for system overpressure defense.
Consolidated Pilot-Operated Safety Relief Valves / ConsolidatedThis revised text restructures the original technical introduction of Gen II 2900/2900 TM POSRVs with polished industrial technical wording, restating its API 526-compliant full-nozzle design, convenient conversion function and multi-medium certification credentials.
Consolidated Pilot-Operated Safety Relief Valves / ConsolidatedThis safety relief valve adopts a non-flow pilot that can be gagged to omit a hydro plug. It achieves zero seat leakage for higher economizer throughput and efficiency, is ASME Section I certified for steam and water to protect economizers in special steam relief conditions, and comes with an integrated snubber to stop valve chatter from pressure surges and water hammer.
Consolidated Pilot-Operated Safety Relief Valves / ConsolidatedThe Consolidated 3900 and 3900 TM pilot-operated safety relief valves adopt a semi-nozzle main valve design complying with API 526 standards. The TM version is a pioneering multi-media certified valve suitable for liquid, gas and steam per ASME Code Case 2787, with standard non-flow pilots and optional pop/modulating pilots to fit varied pressure, sealing and blowdown needs, featuring easy maintenance and reliable, efficient operation.
