HENRY BALL VALVE WITH SIGHT GLASS 5/8

HENRY BALL VALVE WITH SIGHT GLASS 5/8″ 907205 SG

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. Additionally, standard models up to and including 3 1/8 and 76mm sizes are suitable for R290 and A2L gases compatible with the valve materials.

The 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 HPBV is suitable for transcritical CO2 applications.
