Fluidra – Solenoid Coil for 4-Way Reversing Valve – Z200 & PI20 MD2/3/4/5

This is the genuine Fluidra replacement solenoid coil for the 4-way reversing valve fitted to Zodiac Z200 and PI20 pool heat pumps (MD2, MD3, MD4 and MD5 variants). The coil provides the electromagnetic actuation that switches the reversing valve between heating and defrost (cycle-reversal) modes, making it a critical component for reliable all-season operation.

Compatibility

Designed specifically for the Zodiac Z200 Defrost and PI20 Defrost heat pump series, covering all power variants from MD2 through MD5 (PI2021 to PI2051). Always verify your heat pump’s model and serial number against the parts diagram before ordering, as the coil is not interchangeable with other heat pump ranges.

Why Genuine Matters

A faulty or incorrect solenoid coil can prevent the reversing valve from switching, causing the heat pump to lose its automatic defrost capability or fail to produce heat reliably. Using a genuine Fluidra part ensures correct electrical characteristics, a secure mechanical fit on the valve body, and full compatibility with the unit’s control board — protecting your investment and avoiding repeat failures.

Installation

The solenoid coil slides onto the stem of the 4-way reversing valve and is secured in place before reconnecting the electrical leads. Because this work involves refrigerant-circuit components and mains electrical connections, replacement should be carried out by a qualified pool heating or HVAC technician in line with local regulations.
