Refrigerant Boys TZ2 Series Thermostatic Expansion Valve for R407C – Flare Threaded Connections with Sensor Bulb

Description

Precise Flow Control and Mechanical Protection of the Compressor

The Refrigerant Boys TZ2 series thermostatic valve is the key component for optimizing the evaporator’s thermal efficiency and protecting the compressor from dangerous liquid refrigerant return. Designed to meet the thermodynamic characteristics of the R407C zeotropic mixture, it responds extremely quickly to changes in thermal load by modulating the orifice opening and maintaining the set superheat value at a stable level.

Strengths & Advantages:

• Sturdy Body with Flare Connections: Corrosion-resistant forged brass construction with standard SAE flare threaded connections, ideal for quick installations and clean replacements without the need for on-site welding.

• Stainless Steel Thermostatic Element: Diaphragm and head made of stainless steel with precision laser welding, ensuring a lasting airtight seal and resistance to high operating pressures and continuous thermal cycles.

• High-Responsivity Sensor Bulb: The cylindrical steel bulb connected to the coiled capillary tube ensures rapid thermal transmission of the suction line temperature, enabling instantaneous flow modulation.

• Integrated Superheat Adjustment: Equipped with a calibration stem protected by a screw cap to allow the technician to fine-tune the static superheat during testing.

• Compatibility with POE Lubricants: Designed and tested with internal materials and seals that are fully compatible with the synthetic ester (POE) oils used in R407C systems.
