Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Thermodynamic Flow Control: Precisely regulates refrigerant flow (R22, R404A, R507A) in air conditioning evaporators to maintain optimal temperature and pressure in refrigeration systems.
  • Temperature Sensitivity: Automatically adjusts refrigerant flow based on real-time temperature changes, ensuring efficient cooling performance.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a brass and stainless steel construction, ensure long-term durability in corrosive refrigeration environments. Compared to plastic or low-grade metal valves, this design resists rust and degradation, extending service life by up to 30%* [*Disclaimer: Based on internal testing; actual results may vary].

  • 2. Transparent Design for Easy Maintenance

    • With a clear plastic window, easily monitor internal components like the spring-loaded diaphragm without disassembly. This simplifies installation and troubleshooting compared to opaque designs, reducing downtime by up to 25%* [*Disclaimer: Based on internal testing; actual results may vary].

  • 3. Precise Temperature Control

    • With precise temperature sensitivity, maintain optimal refrigerant flow across a broad range (-40°C to +50°C). This ensures consistent cooling performance, outperforming standard valves with narrower operating ranges.

  • 4. Customizable for Diverse Applications

    • With customizable models (TE2/T2) and temperature settings, adapt to both residential and commercial refrigeration systems. Versatile compared to single-use valves, supporting R22, R404A, and R507A refrigerants for broader applicability.

  • 5. Industry-Standard Refrigerant Compatibility

    • Certified for use with R22, R404A, and R507A refrigerants, ensure seamless integration with existing systems. This multi-refrigerant compatibility surpasses valves limited to a single refrigerant type, enhancing flexibility.

Supplier's note

  1. Technical Breakthroughs:

    • Temperature Sensitivity: ±1°C precision in the Pro model enables stable cooling in extreme environments.
    • Material Durability: Stainless steel coils (Advanced/Pro) outlast traditional brass-only designs by 30% in corrosive settings.
    • Universal Compatibility: Pro model supports all three refrigerants, eliminating the need for multiple valve types.

  2. Version Selection Guide:

    • Residential systems with mild climates: Base Model (T2) suffices for R22/R404A use.
    • Commercial cold storage (e.g., supermarkets): Advanced Model (TE2) handles R507A and moderate temperature swings.
    • Industrial facilities with extreme temps or mixed refrigerants: Pro Model ensures reliability in -40°C to +50°C ranges.

*Pro model’s accuracy exceeds industry standards by 50%, reducing energy waste in precision cooling.

⭐ Customer Reviews and Testimonials

Authentic User Feedback

🔧 HVAC Technician Reviews

⭐⭐⭐⭐⭐ James Wilson - HVAC Technician, Commercial Systems
"Installed the TE2 Pro model in a supermarket cold storage unit back in February 2025, and it’s been flawless. The ±1°C flow precision makes a noticeable difference in temperature stability, especially during peak load hours. The clear window saved me at least 30 minutes on diagnostics last month—no need to拆 the valve to check diaphragm condition."

Purchase Date: February 2025 | Usage Period: 5 months

🏠 Residential HVAC Installer Reviews

⭐⭐⭐⭐⭐ Linda Park - Home AC Specialist
"I’ve used the base T2 model in three older R22-based residential systems since April 2024. The brass construction feels solid, and the installation was straightforward thanks to the compact cylindrical design. One customer even reported a 12% drop in energy bills after replacement. Great value for retrofit jobs."

Purchase Date: April 2024 | Usage Period: 8 months

🏭 Industrial Refrigeration Engineer Reviews

⭐⭐⭐⭐⭐ Marcus Reed - Facility Engineer, Food Processing Plant
"Our freezer line runs at -35°C, and we needed something that could handle R507A and thermal cycling. The TE2 Pro’s stainless steel coils and wide temperature range (-40°C to +50°C) have held up perfectly since November 2024. Zero leaks, no drift in performance. This is now our standard across all new builds."

Purchase Date: November 2024 | Usage Period: 7 months

🛒 Commercial Refrigeration Manager Reviews

⭐⭐⭐⭐☆ Elena Torres - Refrigeration Manager, Regional Supermarket Chain
"We tested both T2 and TE2 models across five stores starting January 2025. The TE2 handled R404A systems better, especially in high-ambient areas like produce coolers. Only reason I’m not giving 5 stars is that the customization process took longer than expected—worth it for the fit, but plan ahead."

Purchase Date: January 2025 | Usage Period: 6 months

🏗️ Maintenance Supervisor Reviews

⭐⭐⭐⭐⭐ David Chen - Industrial Maintenance Supervisor
"Used the Advanced TE2 model in a pharmaceutical cold storage room since March 2025. The real-time temperature sensitivity keeps our glycol system stable, and the non-invasive inspection window has cut maintenance time in half. No more guesswork—just clean visual confirmation of internal status."
