Fluidra - pH Minus Injection Valve 3/8"

Fluidra – pH Minus Injection Valve 3/8″

This is the genuine Fluidra replacement pH minus injection valve with a 3/8″ connection, designed for use with AstralPool salt water chlorinator systems that include an automatic pH dosing function. It allows the connected dosing pump to inject pH-reducing chemical directly into the pool’s return line, enabling precise and automated water balance control.

Compatibility

This injection valve is a direct spare part for the Fluidra AstralPool Elite Connect CellGuard pH range, including the pH 12, pH 24, pH 32 and pH 42 models. It is also compatible with a broad range of other AstralPool salt chlorinator systems, including the Smart Next, Neolysis System, and UV Heliox LP series that are fitted with an automatic pH dosing module.

Why Genuine Matters

The injection valve is a critical component in the chemical dosing circuit — a poor-quality or incorrect-fitting replacement can lead to chemical leaks, inaccurate dosing or damage to your chlorinator. Using a genuine Fluidra part ensures exact dimensional compatibility, chemical resistance suited to pH-minus reagents, and reliable one-way flow to prevent back-siphoning into the dosing pump.

Installation

The valve installs inline on the 3/8″ dosing tube that runs from the pH dosing pump to the injection point on the pool pipework. Always isolate the dosing pump before replacing the valve, flush any residual chemical from the line, and verify the flow direction arrow on the valve body before tightening the fittings. Professional installation is recommended if you are not familiar with chemical dosing systems.
