Specifications

Details

The Sanhua RFKH03E-4.8-715A is an angle-shaped thermostatic expansion valve (TXV) specifically engineered for HVAC and commercial refrigeration systems operating on R404A or R507 refrigerants. Its primary function is to precisely regulate the mass flow of liquid refrigerant into the evaporator while continuously controlling the system's superheat.

This specific model features an external pressure equalizer, making it highly effective and accurate for systems that experience significant pressure drops across the evaporator coil. It is built with a durable stainless steel capillary tube and sensing bulb that utilize cross-charge technology to ensure consistent superheat control across a wide range of evaporating temperatures.

Designed for flexibility and easy maintenance, the valve housing accepts interchangeable orifices, allowing technicians to easily swap out the internal orifice to match the exact cooling capacity required by the system.

Rated for a maximum operating pressure of 46 bar (approx.

667 PSI), it provides highly reliable performance in demanding applications ranging from standard air conditioning to low-temperature freezers and ice makers.
