Application & Benefits
The externally equalized design makes this TXV ideal for evaporators with a significant pressure drop, ensuring the valve responds to true evaporator outlet conditions rather than inlet pressure. The 45 PSI MOP charge protects the compressor from high suction pressures during pull-down or warm starts, extending system life and reducing service calls. The 5-foot capillary tube provides installation flexibility, allowing the sensing bulb to be positioned precisely at the evaporator outlet for optimal superheat sensing. The angle body configuration simplifies installation in tight or restricted equipment spaces.
