Five Generations of Cool Touch Technology
Plastic Shell+Brass Waterway
Plastic shell wraps all copper water channels, using air and plastic to insulate
Solid Brass Body
The thermostatic valve core is placed on the left to shorten the distance of the hot water channel, and the cold water is mixed at the hot water inlet end
Zinc Shell+PPA WATERWAY
The PPA plastic water channel is used for water, and the air between the water channel and the metal shell is insulated
BRASS SHELL+PPA WATERWAY
The thermostatic valve core is placed on the left to shorten the distance of the hot water channel, and the cold water wraps around the PPA waterway, so that heat will not be transferred to the surface
SOLID BRASS+PPA SLEEVE
The cold water is between the copper shell and the water channel to isolate heat conduction, and the surface of the shell and the cold water have the same temperature.
