Features:
Relieving capacities certified by National Board of Boiler and Pressure Vessel Inspectors. Certification includes air and steam for Series 800, and air, steam and water for Series 900. BP certification includes air and water.
Valves manufactured in accordance with the requirements of ASME Boiler and Pressure Vessel Code Section VIII and Section III.
Superior seat tightness. Precision lapped flat metal-to-metal seats, or elastomer or TFE O-ring soft seats provide the ultimate in seat tightness. (Elastomer or TFE O-ring seat standard for Series BP.)
Maximum corrosion resistance. Trim components are stainless steel as standard. All 316 stainless steel, Monel®, Hastelloy® and NACE* optional constructions are available.
Spring standardization. Standard Series 800 and 900 pressure relief valves are suitable for inlet temperatures to 750°F [399°C], using a 17-7PH stainless steel spring. Series BP is suitable for inlet temperatures to 400°F [204°C].
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.
Series 900 valves use a single trim design for liquid, gas and vapor services.
Series 900 valves provide reliable blowdown without the need for adjustment.
The Series BP with its balance piston design offsets the effects of variable back pressure on valve set pressure.
Series BP valves can handle applications involving high built-up back pressure.
