Henry Ball Valves Seal Cap 907 Series

Ball valves are used in a wide variety of air conditioning and refrigeration applications. They can be used for both liquid and gas applications. This type of valve is commonly used for isolating purposes. All valves are suitable for CO2, HCFC and HFC refrigerants along with their associated oils.

The ball valve with sight glass (BVSG) combines the traditional ball valve with a sight glass and moisture indicator. A typical location for this combination product is in the liquid refrigerant line. The ball valve is used for isolating purposes; the sight glass for a visual display inside the line and the moisture indicator monitors the moisture content in the system.

The new high pressure ball valve (HPBV) is suitable for transcritical CO2 applications.
