CVC is a pressure-operated pilot valve with a connection that can be used to obtain an indication of the system reference pressure.
CVC valves are used together with a PMC main valve to regulate capacity using hot gas bypass; together with a ICS or PM main valve to regulate max. suction pressure, e.g. as a compressor crankcase pressure regulator; together with a ICS or PM main valve as a pressure limiter, e.g. for hot gas defrost of hot gas lines.
