Product Overview

The Consolidated 1900/P is a direct spring-loaded safety relief valve from the 1900 series, specifically the balanced bellows configuration (P suffix). It is designed for overpressure protection where variable backpressure exists or where emissions must be contained. This model is widely used in refineries, petrochemical plants, and power stations for steam, gas, and liquid service requiring tight seating and reliable pop action.

Features
  • Balanced bellows design – isolates spring chamber from backpressure
  • Full nozzle construction for high capacity and stability
  • Adjustable blowdown ring for precise performance tuning
  • Metal-to-metal seating with optional soft seats
  • Open or closed bonnet options
  • High-temperature capability for steam service
  • Certified tight seating per API 527
