AST RV-6000 changeover valves offer a reliable solution for uninterrupted safety valve maintenance in demanding industrial environments. These three-way valves support continuous plant operation by keeping one safety valve active while the other stays on standby.
This setup avoids costly shutdowns and ensures consistent overpressure protection.
The RV-6000 connects two safety valves to a single pressurized line. One valve stays in service; the other remains ready to activate if needed. This design boosts plant availability and improves system reliability.
Install the RV-6000 upstream of the safety valves, or both upstream and downstream—especially when the outlet connects to a closed discharge header. When using both inlet and outlet valves, a mechanical interlock prevents operational errors during switching.
The compact design simplifies assembly and disassembly. Removable seats allow fast, low-cost maintenance, reducing downtime.
AST changeover valves handle a wide range of applications. They perform well under high temperatures, in cryogenic conditions, and with hazardous or lethal fluids.
