Description
The Copeland Comfort Control (Alco) 058085 Power Element is a sensing and actuation component used in thermostatic expansion valve (TXV) assemblies. In HVAC systems, it is applied within refrigeration and air conditioning circuits where it responds to temperature changes at the sensing bulb and converts those changes into pressure within the element. This pressure movement drives the TXV mechanism to regulate refrigerant flow into the evaporator based on load conditions. It is typically mounted as part of the valve top assembly in commercial and residential cooling equipment, where it supports controlled refrigerant metering.
