Verify Before You Specify

We encourage engineers to validate component performance under their actual operating conditions before committing to a system design.

Free Sample Testing

Request up to 3 sample units of any expansion valve, solenoid valve, or sensor for bench testing in your lab. Samples ship within 48 hours from regional stock. No purchase obligation.

Application Engineering Review

Submit your system schematic, operating parameters (evaporating/condensing temperatures, refrigerant type, capacity range), and our engineers will provide a detailed sizing report with recommended models, safety margins, and alternative options within 3 business days.

AHRI-Certified Performance Data

All published COP, EER, and capacity ratings for our components are tested per AHRI Standard 760 (solenoid valves) and AHRI Standard 750 (thermostatic expansion valves). Test reports with full methodology and environmental conditions are available upon request.

Expansion Valve Selection: Key Dimensions

Selection Factor TXV (Thermostatic) EEV (Electronic)
Superheat Control Accuracy ±2-3 K typical ±0.5-1 K typical
Refrigerant Compatibility Requires charge-specific element; limited to single refrigerant per valve Software-configurable for multiple refrigerants including R-290 and R-744
Part-Load Performance Reduced accuracy below 50% load; hunting possible Maintains accuracy across 10-100% load range via stepper motor control
Installation Cost Lower (no wiring, no controller required) Higher (requires controller, wiring, and configuration)
Best Application Fit Constant-load systems, simple circuits, budget-constrained retrofits Variable-load systems, multi-circuit units, BMS-connected installations
