API 526
Dresser Consolidated 3900/3900 TM Series Pilot-Operated Safety Relief Valves (POSRVs) feature a semi-nozzle main valve design that meets API 526 center-to-face dimensional requirements for POSRVs. The 3900 Triple Media (TM) Series is one of the first POSRVs engineered to perform on liquid, air/gas, and steam media and is multi-media certified to meet multiple media capacity stamping per ASME B & PVC Code Case 2787. Both 3900 series come standard with a non-flowing pilot valve that is suitable for compressible and incompressible fluids. Optional pilot valve constructions are available for either pop or modulating action functionality to meet various pressure range, seat tightness, and blowdown requirements. Highly versatile, these valve technologies offer ease of maintenance, high reliability, flexibility, and efficient operation and performance.
