The main property:
1.the valves are designed with double slopping surfaces. Functioned
by the springs, they automatically adjust the tightness among the
valve seats, valve body and ball body to make all of them have excellent
tightness under the medium and low pressure.
2. the tightness between the stems, and the contact of the valve
cover uses compact among the parking surface stem and cover shoulder
surface to reduce the opening moments.
3.the valves are of integral top loading types, so it's unnecessary
to disassemble them from the pipes. Just remove the cover , you
can repair them and change the spare parts to make the maintenance
more easy.
