Not the appearance but the cartridge is the
key point to choose the faucet
Currently on the market there have ceramic
valve core, ball valve core and rubber core. Ceramic
cartridge core is a new generation of valve core material, especially
the import ceramic chip, good sealing, stable physical performance, and long
service life, normal is beyond 10 years.
Faucet main body is made of bronze casting.
Good bibcock comes out by integral mould, knocking sound is very depressing. If
the sound is very crisp, is must be made of stainless steel material, means
less quality. Imported faucet brand normally have a hard imprint on the splash
head periphery.
Faucet surface is coated for titanium
plating chromium, plating, spray paint... observe plating surface, if it is
shining. The plating chromic layer of imports faucet is thicker than domestic, not
easily fall off and oxidize.
There are two kind of Faucet controls handle,
single
handle faucet and double handle. The characteristics of the single
handle is easy to control with simple structure; double handle need two hands to
adjust hot or cold water. But design type can suit for more situations (such as
undercounted tap, the bibcock of massage crock).
The pressure of Single handle
faucet will rise rapidly at the moment of open and closed. If the cupreous
content of the products is not high, it is easy to damage for fail to stand the
pressure of inflation, so single handle faucet is being used, should slowly
open and shut. Range of compression of double handle faucet is big, hydraulic
be released slowly, so this problem can be ignored.
