Hanna Instruments PCA Solenoid Valve 24 VAC / 50 Hz (HI70489)

Hanna Instruments PCA Solenoid Valve 24 VAC / 50 Hz

The HI70489 is a genuine Hanna Instruments replacement solenoid valve rated at 24 VAC / 50 Hz, designed specifically for the Hanna PCA series of automatic pool water analysers and controllers. It is a critical internal component that controls the flow of water or reagent within the analyser’s measurement circuit, ensuring accurate and repeatable results. Keeping a genuine spare on hand minimises system downtime when scheduled maintenance is due.

Compatibility

This solenoid valve is compatible with the Hanna PCA310, PCA311, PCA320, PCA321, and PCA330 automatic pool analysers and controllers — the PCA series used for continuous monitoring and control of chlorine, pH, ORP, and temperature in commercial and public swimming pools. Note that the 50 Hz rating makes this the correct version for European mains-powered installations; a separate 60 Hz variant (HI70488) is available for other markets.

Why genuine matters

Using an official Hanna Instruments spare part ensures dimensional and electrical compatibility with your PCA analyser, protecting calibration integrity and the accuracy of your dosing control. Third-party substitutes may not meet the precise operating voltage and frequency tolerances required by the PCA platform, risking measurement errors or premature failure.

Installation

Installation should be carried out by a qualified pool technician or service engineer familiar with the Hanna PCA series. Always isolate the analyser from the mains supply and shut off the water circuit before replacing the solenoid valve. Refer to the relevant PCA service manual for the correct torque settings and wiring procedure.
