series 870

Series 870 Safety Valve – ASME Section I

The Series 870 is intended for critical overpressure-protection applications in steam-generating equipment governed by ASME Boiler and Pressure Vessel Code, Section I, including boilers, superheaters, and steam drums, within the applicable product design limits.

These services require careful consideration of set pressure, steam pressure and temperature, required relieving capacity, materials, and the applicable code requirements. Reliable operation of the pressure-protection system is essential to safeguard pressure-containing equipment and personnel. Inadequate relieving capacity or failure of the overpressure-protection system can result in severe equipment damage, major operational disruption, and serious safety consequences.

Selection and verification must be based on the relevant boiler design conditions, required relieving capacity, and applicable inspection and testing requirements. Any claim of ASME Section I conformity, certification, or authorization must be supported by the product’s actual design documentation and applicable certification records.
