ROTARY GLOBE CONTROL VALVES

Rotary Globe Control Valves -
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.  The biggest users of these valves are building controls companies, systems integrators, college and corporate campuses, data centers, food manufacturers and other companies who want to save energy by having tighter control of their processes.

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.  We offer our own energy saving actuator and also actuators from leading companies like Belimo, Honeywell, Siemens, Johnson Controls, KMC and others.  Contact us for more information.
