The Sarasin-RSBD® Starvalve series of changeover valves provides a safe and efficient method of switching from an active to a standby pressure relief valve.
Due to the changeover valve design, no seat lapping is required for maintenance, meaning there are minimal spare parts and a reduced cost of ownership. It reduces the risk of a pressure relief valve chattering from excessive pressure drop through traditional shuttle type changeover valves. The Sarasin-RSBD® Starvalve is a rotor type changeover valve which maintains a pressure drop of pressure below 3% through its body. This changeover valve is designed for use in refineries within the petrochemical and cryogenic industries.
