The Parker OE series thermostatic expansion valve utilizes balanced port construction to provide optimum operation on medium to large Tonnage air conditioning and refrigeration systems. 2-brass body styles with copper OD connections and a removable thermostatic power element provide the stability and control required in a variety of applications, especially where there are wide changes in load conditions. Body style 1 (Small O) has a R-22 nominal capacity up to 30 Ton, while body style 2 (Large O) extends the capacity to 70 Ton R-22.

White Rodgers Cooling Controls TXVs are designed for a wide range of air conditioning, refrigeration, heat pump, and chiller applications. Copeland uses stainless steel power elements that are unsusceptible to corrosion. We offer products with conventional, as well as balanced ported designs that are advantageous when applied to systems with large load variations and/or floating head applications. Copeland also manufactures bi-flow designs for use in heat pumps and many of our TXVs have a take-apart design for ease of service. Copeland thermal expansion valves cover a wide range of nominal capacity, from 1/2 - 100 Ton.
