VBall Control Valves -
V-Ball Control Valves featuring high rangeability with 300:1 turndown ratio (compare to 10:1 butterfly and 50:1 globe valve) for excellent control of steam, hot water, chilled water and glycol mix for 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 controllable flow is also greater than a butterfly valve of the same size as the butterfly valve is limited to 45-50 degrees open for controllable flow.  This valve can also be used with steam and has a higher shutoff pressure than other valve types.

Valves are available in 3/4" thru 14" size and 150#, 300# flanged, wafer and threaded end connections.  Class VI ANSI leakage class shutoff.  Carbon steel, stainless steel and other materials available for a body option.  Stainless steel ball and stem is standard.  Shaft and segmented ball pinned and welded.  Indication of flow direction. Spring loaded teflon v-ring packing, maintenance free design with 450 deg f rating.  Graphite seat rated for 300 psi steam rating.  ANSI B16.10 Face to Face dimension. Can be supplied with electric, electronic, or pneumatic actuator.  Contact us for more information.
