Thermostatic Expansion Valves – Universal Refrigeration Models

Description

Our complete selection of Thermostatic Expansion Valves offers reliable refrigerant flow metering for residential split air conditioners, commercial cold rooms, supermarket display cases, and industrial process chillers. Constructed with heavy-duty metal alloy bodies, stainless steel capillary bulb assemblies, and precision-engineered power heads, these valves automatically regulate liquid refrigerant injection based on evaporator load demand. Available in both internally equalized and externally equalized designs, our catalog covers a full range of cooling capacities and connection styles.

Model Series & Configurations

Technical Specifications

Key Features

• Universal Component Compatibility: Standardized physical dimensions and connection threads for easy drop-in field replacement.

• Precise Superheat Regulation: Maintains target evaporator superheat across varying thermal load conditions.

• Interchangeable Orifice Assemblies: Selectable orifice sizes allow precise tonnage and capacity matching for custom and repair installations.

• Compressor Protection: Prevents liquid refrigerant slugging and unvaporized liquid floodback into the suction line.

• Corrosion-Resistant Assemblies: Durable metal alloy valve bodies paired with stainless steel diaphragm power heads.

Supported Applications

• Commercial Refrigeration: Cold storage warehouses, walk-in coolers, freezer rooms, and supermarket racks.

• Residential & Light Commercial HVAC: Split air conditioners, heat pumps, and packaged cooling units.

• Optional: Interchangeable Orifice Insert (sold separately or as part of matched valve kit)

Important Buyer Verification Notes

Notice for Technicians & Contractors: Match replacement valves by model code, refrigerant type, cooling capacity (tonnage/kW), connection size, and equalizer type (internal vs. external). Wrap the valve body with a damp cloth during brazing to prevent thermal damage to the internal power head diaphragm.

Frequently Asked Questions (FAQs)

What types of expansion valves are available in this lineup?

We supply both internally equalized (TE2 style) and externally equalized (TEX2 style) thermostatic expansion valves across various connection sizes and capacities.

How do I choose between internal and external equalizer valves?

Use an internally equalized valve for small evaporators with minimal pressure drop. Use an externally equalized valve for large, multi-circuit evaporators or systems with significant internal pressure drops.

Are the orifices included with the valve body?

Some models are supplied as complete assemblies, while series like the TE2/TEX2 use separate interchangeable orifices to let you customize capacity.
