These high-capacity V-ported control ball valves offer automatic throttling capability with flexible shutoff options, simplified maintenance needs, and enhanced operational reliability.

The V-Max* rotary control valve offers high-capacity, heavy-duty automatic throttling capability.The valve’s advanced design features offer substantial benefits, including:

•  Simplified alignment. The valve’s integrally cast raised face flanges (in compliance with ASME 150 or 300 Class standards) eliminate the need for long tie rods, significantly simplifying the alignment process.
• Installation flexibility. To meet a variety of application needs, the valve is available with two different face-to-face dimensions: standard construction complies with ISA S75.04 and IEC 534-3-2 standards and a short pattern complies with the ANSI B16.
• Enhanced flow capacities. A straight-through flow pattern provides exceptional capacities, while the patented dual-characterized V-port ball combines an equal percentage flow characteristic with highcapacities and greater than 500:1 rangeability.
• Excellent leakage control: A standard EF(emission free) seal packing system provides long-term, zero leakage† shaft sealing performance.

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.
