3.1. PROPER USE
The purpose of the CEV-S Series valve is to be permanently installed in a vapour compression refrigeration appliance,
with or without reverse cycle features, as the expansion (lamination) element to reduce the condensing pressure down
to the value of the evaporating pressure. The CEV-S valve body must be securely coupled to one of the available CEC
Series stator, connected to a properly designed control system.
