SARASIN-RSBD®

9 Series Pressure Relief Valve

The Sarasin-RSBD® 9 Series is a compact Spring Loaded Pressure Relief Valve offering a versatile design with premium performance. The Sarasin-RSBD® 9 Series range of Spring Loaded Pressure Relief Valves are available in both conventional and balanced bellows designs. These compact spring loaded safety relief valves can be used in vapor, gas, liquid, or steam applications.

The Sarasin-RSBD® safety relief valves are designed to provide high integrity performance and repeatability by their use of an integral full, one-piece nozzle, a self-aligning top-guided disc & disc-holder, and a single adjusting ring for blowdown setting. The 9 Series pressure relief valves are suitable for use within the power industry as well as for cryogenic and industrial gas processes.
