Refrigerant Boys TS2 Series Thermostatic Expansion Valve for R404A / R507 – Flare Threaded Connections with Sensor Bulb

Description

Reliability and Constant Thermostatic Control for the Cold Chain

The Refrigerant Boys TS2 series thermostatic valve is the key component for optimizing the cooling performance of static and forced-draft evaporators, protecting the compressor from the risk of liquid slugging. Calibrated to respond promptly to the pressures and evaporation curves typical of R404A and R507 refrigerants, the valve modulates the opening of the flow passage as the thermal load varies, ensuring uniform wetting of the heat exchange surface and stable superheat even under severe sub-zero operating conditions.

Strengths & Advantages:

• Sturdy Brass Body with Flare Fittings: Solid, corrosion-resistant construction with male SAE flare threaded connections, which facilitates installation, maintenance, and quick replacement without requiring flame brazing.

• Stainless Steel Thermostatic Diaphragm: Laser-welded stainless steel sensing element assembly, designed to withstand tens of thousands of thermal cycles and pressure surges without deformation or loss of internal charge.

• High-Conductivity Sensor Bulb: The cylindrical bulb ensures an immediate temperature reading of the suction line, promptly transmitting pressure changes to the diaphragm via the flexible capillary tube.

• Fine-Tuning Adjustment Screw: Features a manual adjustment stem (protected by a hermetically sealed cap) for precisely setting and optimizing the static superheat value during system testing.

• Compatibility with POE Lubricants: Designed with materials and seals that are completely inert toward synthetic ester oils (POE) commonly used in R404A/R507 refrigeration systems.
