Copeland 065942 R410A 2-Ton TXV w/ Internal Check Valve & Bleed Hole, 3/8″ x 1/2″ Sweat, 30″ Cap Tube, MOP 195 PSI

Description

Copeland 065942 Thermal Expansion Valve Overview

The Copeland 065942 (model AACE 2 SW195 30IN 3/8 X 1/2 ODF S/T) is a precision-engineered Thermal Expansion Valve (TXV) designed specifically for R410A refrigerant systems. Rated at 2-ton capacity, this externally equalized valve delivers accurate refrigerant metering and reliable system performance in residential and light commercial air conditioning applications. The integrated internal check valve and bleed hole provide added system protection and balanced operation during off-cycle equalization.

Application & Benefits

The external equalizer port ensures accurate superheat control even in systems with significant pressure drop across the evaporator, making this TXV ideal for multi-circuit or longer evaporator coils. The 195 PSI MOP charge protects the compressor from operating at excessively low suction temperatures during startup or abnormal conditions — a critical feature for R410A systems operating at higher pressures. The built-in internal check valve eliminates the need for a separate check valve in heat pump or cooling-only systems, simplifying installation and reducing component count. The bleed hole facilitates pressure equalization between the high and low sides during the off-cycle, reducing startup torque on the compressor.
