Starflow-V (PV Series) Pressure Relief Valve 3D

Sarasin-RSBD®

Starflow-V (PV Series) Pressure Relief Valve

The Sarasin-RSBD® Starflow V Pressure Relief Valve is designed for steam boiler applications and provides anti-seizing, rapid lifting, and blowdown performance.

The Starflow V Pressure Relief Valve compliments the existing Starflow P and Starsteam offerings.

The additional option allows boiler manufacturers and plant operators to deal with a single supplier for multiple sizes and pressure conditions ranging from 1 to 8 inches (1 bar (14 psig) to 370 bar (5,366 psig)).

The Starflow Pressure Relief Valve range has been designed to work in a number of processes including multipurpose flow control and pressure relief within the power industry. Furthermore, with the addition of the Starflow V, Trillium Flow Technologies™ now offers its customers a fully inclusive product range available for boiler applications up to supercritical operational levels.
