Sarasin-RSBD Starflow (V Series) Pressure Relief Valve

Sarasin-RSBD Starsteam (V Series) Safety Valve

The Starsteam Spring Loaded Safety Valve is designed to reliably meet the stringent requirments of ASME Boiler and Pressure Vessel Code Section I for Power applications.

The Starsteam Safety Valve is designed to meet the rigorous process conditions which are essential for steam boilers. This spring loaded safety valve is used in superheater and reheater applications and is specially engineered to provide fast response to overpressure and blowdown requirements. The Starsteam safety valves are designed to provide high integrity performance and repeatability particularly at high pressure and high temperatures in power plants as well as oil and gas boiler applications. This safety valve features a Stardisc design which guarantees perfect tightness at high temperatures as well as repeated and accurate positioning on the nozzle.

Key benefits/features:

A specially engineered internal design provides the fast response overpressure and blowdown requirements which are demanded by ASME BPVC Section I code of practice
The valve is for use in boiler drum, superheater and reheater applications
Flanged or butt-weld inlet connections
Flow capacity tested by the US National Board and carrying the ASME V code stamp (full lift and restricted lift)
Thermoglide design eliminates the risk of seizing or sticking of internal parts.
Thermoglide design improves the gliding characteristics of internal parts thus enabling the valve to achieve its full lift and re-seat point within the fastest possible time.
Stardisc disc lip design guarantees perfect tightness due to its flexibility at high temperature.
Starsdisc low loading point guarantees repeated and accurate positioning on the nozzle
Dual Adjusting Ring to adjust the accumulation chamber volume and guarantee short and fast action blowdown characteristics.
Seal welded semi-nozzle design
Pre-drilled yoke mounting surface for in-situ electronic valve testing.
