Safety Valve SMS-7100

 

Description

AST type SMS-7100 is a high capacity safety valve specifically designed for steam service. These safety valves are usually installed on steam power boiler for overpressure protection.
The double rings design allows for relieving capacity at 3% overpressure and for a precise control of valve closing.
Maintenance resources and repair times are minimized thanks to the superior tightness provided by the specific flexible seat design of the disc.
SMS-7100 safety valves are available either with flanged or welding neck inlet connection.
