Valve Specifications

The RUREK control valve is a single seat globe valve featuring a solid, non-metallic, machined body. This construction incorporates "push down to close" valve plug action. It is designed to handle most of the highly corrosive and toxic fluids. Within its temperature range, the RUREK control valve has virtually bubble-tight shutoff, while handling fluids with 150 PSIG (10 KG/CM2G) maximum inlet pressure.

In line maintenance procedure with quick-change trim, full-size and restricted-capacity orifices, optional body and trim materials and the compatibility with Fisher Controls actuators and accessories, make the RUREK control valve a prime choice for applications where "tough to handle" corrosive fluids are to be controlled.
