Family Description
The Schneider Electric VB Series globe valves are available in 1/2" to 2" threaded bronze body VB-7XXX models, or in 2 1/2" to 6" flanged cast iron body VB-8XXX models. The flanged valves have a patented balanced plug design. The balanced plug design allows water or steam to flow through the valve plug, equalizing the pressure on the top and bottom of the plug which greatly reduces the force required to operate and close these larger size valves.The VB Series valves are designed for control of chilled water, hot water, or steam in the HVAC industry and have a long history of high quality and reliability. They are available pre-assembled with electric or pneumatic actuators, or available without actuator for field assembly.
