Refrigerant Boys TEN2 Series Thermostatic Expansion Valve for R134a – Flare Connections with 1/4″ SAE External Equalization

Description

Maximum Thermodynamic Stability for Evaporators with High Pressure Drop

Unlike internally equalizing valves, the Refrigerant Boys TEN2 series features an external pressure equalization line (1/4″ SAE Flare), making it indispensable for systems equipped with liquid distributors, extended evaporator coils, or circuits with significant internal pressure drops. By sensing the actual pressure at the evaporator outlet, the valve instantly compensates for internal pressure drops within the coil, preventing delayed valve openings, thermal oscillations (hunting), and dangerous liquid slugging back toward the compressor.

Strengths & Advantages:

• External 1/4″ SAE Flare Equalizer: Ensures an accurate, unbiased reading of the evaporator pressure downstream of the coil, optimizing the R134a gas supply even in complex or multi-channel systems.

• Forged Brass SAE Flare Threaded Body: Facilitates quick installation and on-site replacements without requiring an open flame or brazing, preventing thermal degradation of internal parts.

• Stainless Steel Thermostatic Element: The head and diaphragm are joined by high-precision laser welding, ensuring a long-lasting hermetic seal that withstands vibrations and pressure surges.

• Fast-Response Sensor Bulb: The compact cylindrical bulb rapidly transmits temperature changes detected in the intake line to the diaphragm, allowing for instantaneous modulation of the flow cross-section.

• Fine-Tuning Adjustment Screw: Equipped with a stem for manual calibration of static superheat, protected by a hermetically sealed threaded metal cap.

• Inert to POE and PAG Lubricants: Compatible with synthetic ester oils (POE) used in stationary refrigeration systems and with PAG oils used in special air conditioning and transportation applications.
