Sanhua solenoid valve expands R744 range
29th July 2025
SPAIN: The CDF-U solenoid valve expands Sanhua’s R744 product range to meet the growing demand for efficient and sustainable CO₂ refrigeration solutions.
Specifically designed for a maximum working pressure of 140bar, the CDF-U series normally closed solenoid valves come in two versions – direct-acting and pilot-operated.
They are mainly used in applications such as oil circuits, hot gas bypassing, and thermal defrosting in CO2 transcritical systems.
Maximum working temperature is 150°C and the maximum operating pressure differential in the oil is up to 110bar.
It is applicable to refrigerant circuits (gaseous and liquid) and pure oil circuits. The stainless-steel valve body is paired with two copper connecting pipes, featuring a lead-free design. The valve body is detachable for ease of maintenance.
