BALL VALVES
The function of a Ball Valve is to provide isolation in liquid and gas
applications with single or bi-directional flow where little restriction
is desired.
Applications
Ball valves are used in a wide variety of refrigeration and air conditioning
applications. They can be used for both liquid and gas applications. This
type of valve is commonly used for isolating purposes. 937 series ball valves
are suitable for use with HCFC and HFC refrigerants and their associated
oils, as well as other industrial fluids non-corrosive to brass, steel, copper,
Teflon and synthetic rubber.
