Electronic Expansion Valve for Norsup SP28T / SP35T - 7036942

Bosta – Electronic Expansion Valve for Norsup SP28T / SP35T

This is the genuine OEM electronic expansion valve (EEV) designed specifically for the Norsup Silent-Pro SP28T and SP35T inverter pool heat pumps. The electronic expansion valve precisely meters refrigerant flow through the heat pump’s refrigerant circuit, enabling the inverter compressor to modulate heating capacity efficiently across varying ambient conditions. Replacing a faulty EEV restores correct refrigerant metering and optimal heat pump performance.

Compatibilità

This valve is an exact-fit spare part for the Norsup Silent-Pro SP28T (28 kW, 230 V single-phase) and SP35T (35 kW, 400 V three-phase) inverter pool heat pumps. It is not interchangeable with other SP-series models. Always verify your heat pump’s model designation before ordering.

Perché l'autenticità è importante

The electronic expansion valve is a precision refrigerant component — tolerances in flow capacity and electronic actuation are model-specific. Using a genuine Bosta-supplied part ensures correct refrigerant metering, maintains the inverter’s ability to vary heating output efficiently, and avoids pressure faults or compressor protection trips that can result from an incorrectly rated aftermarket valve.

Installazione

Replacement of an electronic expansion valve involves opening the refrigerant circuit and working with pressurised refrigerant (R32). This work must be carried out by a qualified F-gas-certified refrigeration technician using appropriate recovery and recharge equipment. Correct operation should be verified by checking system pressures and EEV response after recharge.
