Rotary Control Valves
Maxum™ Rotary Control Valves (RCV)
Product Description
Major Markets: Pulp & Paper, Chemical, Power, Petroleum, Refining
Design Features: The Maxum™ RCV Rotary Control valve is an eccentric rotary control valve for throttling liquids, gases and slurries. It combines precise throttling accuracy and control over a full 90° of rotation. Tungsten carbide coated trim components and design features provide superior erosion resistance. The RCV valve is designed for bi-directional flow capability and includes four trim options for flexibility. It is designed for ease of maintenance with no internal threaded components and self-aligning seat and plug. Flanged or flangeless designs to meet ANSI or ISA face-to-face dimensions.
