Nuova Simonelli Expansion/Retention Valve CO10

Nuova Simonelli Expansion/Retention Valve – CO10 (Small, 1/4")

This is the smaller CO10 retention/expansion valve sized for 1/4" fittings, used inside expansion valve assemblies, not the larger valve at the bottom of the water reservoir.

SPECIFICATIONS

• Fits inside 1/4" fittings only
• Current production uses a white plastic center sealing piston (earlier versions were green)

COMPATIBILITY

• Fits: Nuova Simonelli expansion valve assemblies (1/4" fittings only)
• Replaces: Nuova Simonelli #01000090

INSTALLATION

Simple DIY swap once the expansion valve is opened up.

PRO TIPS

• Confirm which valve you're servicing before ordering, this small CO10 fits inside the expansion valve itself, not the larger retention valve at the base of the reservoir; the two look similar but aren't interchangeable.
• Don't be alarmed if the new piston is white instead of green, Nuova Simonelli changed the piston material/color, but form and function are identical.
