Fluidra - Expansion Valve Solenoid Coil UKV A053 for Z300 TD8 Heat Pump

Fluidra – Expansion Valve Solenoid Coil UKV A053 for Z300 TD8 Heat Pump

This is the genuine Fluidra replacement solenoid coil (UKV A053) for the electronic expansion valve fitted to the Zodiac Z300 TD8 pool heat pump. The coil generates the electromagnetic field that actuates the expansion valve, precisely regulating refrigerant flow through the heat pump’s refrigeration circuit. A faulty or failed coil will prevent the expansion valve from operating correctly, leading to loss of heating performance or system shutdown.

How It Works

In a pool heat pump, the expansion valve controls the amount of refrigerant released into the evaporator, and the solenoid coil is the electrical actuator that drives it. When energised, the coil moves the valve’s internal mechanism to meter refrigerant flow with precision, which is essential for maintaining efficient heat transfer and stable pool water temperatures. Replacing a worn or burnt-out coil restores correct valve operation without the need to replace the entire valve assembly.

Compatibility

This coil is a factory spare part for the Fluidra (Zodiac) Z300 TD8 pool heat pump. Always cross-reference your heat pump’s model number and the existing coil reference before ordering, as different Z300 variants may use different coil specifications. If in doubt, consult your installer or Fluidra’s official spare parts catalogue.

Why Genuine Matters

Using a genuine Fluidra OEM coil ensures correct electrical characteristics (impedance, voltage rating) and a precise mechanical fit on the UKV expansion valve body. Aftermarket alternatives may not match these tolerances, risking poor valve control, refrigerant circuit inefficiency, or premature failure. This part is supplied directly through Fluidra’s official spare parts network for assured quality.
