Camflex - Fluid Tech MASONEILAN

Masoneilan 35002 Series Camflex™

Rotary Control Valve

When the original Camflex was introduced in 1968 it created a revolutionary new category of control valves -the Rotary Globe. This new type of valve converged the best control features of a conventional globe valve with a rotary action to produce a valve capable of replacing at least 80% of the control valves in use at that time.

Many improvements and enhancements have been made since that time, with over 1 million Camflex valves installed in a wide range of process control applications. Everything from the most basic water applications up to severely erosive services that would tear other valves apart. The Masoneilan Camflex valve is designed first and foremost to be an excellent control valve and has proven to truly be a Universal Rotary Globe control valve.

CAM-flex

The heart of the Camflex valve is its eccentric plug. The eccentrically rotating, double offset plug CAM’s into and out of the seat. This camming action eliminates friction throughout its rotation since the plug moves away from the seat as it opens, unlike other rotary valve types. This ensures precise control at all openings.

Cam-FLEX

The plug is offset such that the trailing edge of the plug face will contact the seat ring first when closing. Additional plug rotation causes the plug arms to flex slightly, moving the plug face into full contact with the seat. This flexing action ensures tight long-term seating with smooth seating/unseating action.

Linear Flow Characteristic with Higher Turndown

Camflex’s linear flow characteristic provides a slight modification as the plug approaches the seat. As the plug cams into the seat, the rate of change in flow is reduced gradually until the plug contacts the seat. This provides a Cv ratio of 100:1 for stable operation over a wider range in flow. Most traditional globe style control valves offer 50:1 maximum.

Integral Extension Bonnet

The integrally cast extension bonnet provides effective radiation of heat in high temperature applications to allow the use of low-friction TFE packing materials across the full rated service temperatures of -196˚C to 400˚C (-320˚F to 750˚F). Graphite based packing is available as an option for fire-safe applications.
