AST – Changeover Valve RV-6000

AST RV-6000 changeover valves are three-way devices for flow selection in a pipeline, typically used to connect two safety valves to a single pressurized system. These devices ensure the possibility to have one safety valve always in operation and one in “stand-by”, ready to come into operation. These changeover valves are recommended to increase plant availability or to avoid plant shutdown, avoiding any relevant economic damage.
RV-6000 changeover valves can be installed individually upstream of the safety valves or upstream and downstream of the safety valves, when outlet is connected to a closed header. If inlet and outlet changeover valves are used, a mechanical interlocking system prevents human error during the operation.
Our simple design allows easy assembly / disassembly; easy removable seats allow quick and economic maintenance.
These valves are suitable for a wide range of applications, such as high temperatures, cryogenic service, lethal fluids and many others.
