  • Общие характеристики

    The Carel E4V electronic valve is designed to act as the expansion device on medium/high capacity chillers and air-conditioning systems, up to a cooling capacity of 280 kW.
    Reliability, wide control capacity, fluid flow in both directions: these three features are all ensured by the E4V expansion valve, satisfying the need for a high product quality combined with operating and installation versatility.
    The innovative characteristic of the E4V is the incorporated sight glass, used to monitor movement of the movable element and refrigerant flow inside the circuit. In addition, the valve is made from modular elements assembled during installation, to simplify maintenance and inspection of the components.

    The Carel product line includes the E4V-H HOT GAS version, available in two sizes, 85 and 95; this is suitable for high temperature applications, thanks to the innovative introduction of a movable element made entirely from composite material.
