GZJA sub assembly series: ball valve + check valve [R744 sub-critical]

GZJA sub-assemblies include a CBVT ball valve (PS=140bar) and a BCV check valve (PS=90bar); they are typically used in commercial CO2 refrigeration applications, to isolate specific parts or components present in the system. With the ball valves in closed position the refrigerant cannot achieve the isolated component, but it can be suck up through the check valves. A typical application is keeping evaporator coil isolated without over pressurizing due to warm up.
