ROTARY GLOBE CONTROL VALVES

Rotary Globe Control Valve Advantages -
Eccentric Rotary V-Ball Control Valves featuring high rangeability with 300:1 turndown ratio (compare to 100:1 Vball, 50:1 Globe Valve: and 10:1 Butterfly Valve) for excellent control of steam, hot water, chilled water and glycol mix for commercial building control systems and many industrial process control systems.  
One advantage of this valve type is cost savings: e.g. You can use a 1-1/2" vnotch ball valve instead of a 3" traditional globe valve as the cv is much greater in this valve.  The range of controllable flow is also much greater than a butterfly valve of the same size as the butterfly valve is limited to 45-50 degrees open for controllable flow. The flow charactoristic is equal percentage.  This valve can also be used with steam and has a higher shutoff pressure than other valve types.   A dual valve configuration for 1/3, 2/3 control gives extended range for accurate control over a wide load, like seasonal fluctionations.  The valve has Class 6 Shutoff. Small Actuators can be Used.
