Emerson Alco 062036 Expansion Valve

The Emerson Alco 062036 (THR 100 HC) is a high-capacity 100-ton thermal expansion valve engineered for balanced port performance in large-scale commercial and industrial HVACR systems. Designed specifically for R22 refrigerant, this TXV ensures precise superheat control across a medium temperature charge range, preventing liquid slugging and optimizing evaporator efficiency. This model features a 10' capillary tube length for flexible remote bulb placement and is provided less flange, allowing technicians to utilize existing hardware or select specific bolt-on connections. The stainless steel power assembly protects against corrosion and fatigue, ensuring consistent Diaphragm movement under fluctuating head pressures. For contractors managing industrial chiller maintenance or high-output refrigeration plants, the 062036 delivers the reliable modulation required for high-load applications where HVAC system efficiency and strict superheat maintenance are critical for compressor longevity.

• 100-Ton Nominal Capacity: Optimized for high-tonnage industrial systems requiring precise refrigerant flow modulation.
• Balanced Port Design: Compensates for varying head pressures to maintain stable superheat settings during part-load conditions.
• Medium Temp Charge: Specifically calibrated for standard refrigeration and air conditioning applications using HCFC-22.
• 10-Foot Capillary: Extended capillary length provides necessary reach for large evaporator coils and complex piping layouts.
• Field Serviceable: The "less flange" configuration allows for rapid swap-outs of the valve body without disturbing primary piping.

What is the primary function of the balanced port in the THR 100 HC?
The balanced port design neutralizes the effect of pressure drop across the valve, ensuring that the expansion valve orifice modulates based on evaporator load rather than changes in head pressure.

Can this valve be used with refrigerants other than R22?
This specific model is calibrated for the pressure-temperature curve of R22 refrigerant. Using it with different refrigerants may result in improper superheat control and potential system damage.

Does this unit come with the mounting gaskets and bolts?
The 062036 is sold as a "less flange" unit. You will need to reuse your existing Alco flange bolts and gaskets or purchase a compatible flange kit separately for installation.
