Schneider Electric (Barber Colman) VB-7224-0-4-9 Globe Union Suction Valve 1-1/4" Sweat 20Cv

Schneider Electric (Barber Colman) VB-7224-0-4-9 is a 1-¼ inch Globe Union sweat suction control valve used in HVAC systems. This valve controls the refrigerant flow in refrigeration and air conditioning systems. The fluid flow capacity is shown by its "Cv" value of 20. An internal spring and a pressure-sensing mechanism power the valve. More refrigerant can flow when the spring forces a valve stem open on the suction side of the compressor when the pressure decreases below a predetermined point. On the other hand, pressure above the set point causes the valve stem to close, limiting the flow of refrigerant.
