Crosby Pressure Relief Valves, Direct Spring Process Valves, Crosby Series 800 and 900 OMNI-Trim Pressure Relief Valves

Adjustable blowdown design for medium flow of air, gas, vapor and steam applications. External precise blowdown adjustment provides shorter blowdown than the Series 900. Full nozzle design. Available with metal or O-ring seat.

Features & Benefits:

  • Relieving capacities certified by National Board of Boiler and Pressure Vessel Inspectors. Certification includes air and steam.

  • Superior seat tightness. Precision lapped flat metal-to-metal seats, or elastomer or TFE O-ring soft seats provide the ultimate in seat tightness.
  • Maximum corrosion resistance. Trim components are stainless steel as standard. All 316 stainless steel, Monel®, Hastelloy® and NACE* optional constructions are available.
  • Spring standardization. Suitable for inlet temperatures to 750°F [399°C], using a 17-7PH stainless steel spring.
  • Positive built-in lift stop.
  • Fewer parts result in increased reliability and ease of maintenance.
  • Series 800 pressure relief valves have an external blowdown adjustment allowing for short blowdown, smaller differential between operating and set pressures, and reduced product loss.
