1. Structural characteristic: position indication, lock structure
three-prevention structure.2. Whole structure has the position indication lock
set, fireproofing, anti static, and preventing stem from rush out.3. Obvious
indication of switch position: sphere, stem and hand holder, valve turn off4.
Position lock: in order to avoid wrong operation, set up the padlock set, may
lock the switch position when necessary. >>
This product is produced in according to API standard in designing manufacture
and checking; it is compact in pattern, reliable in sealing and easy to operate;
it is used in petroleum, chemical, electric power, metallurgy and other industries. >>
.is widely applied in these field such as petrochemistry,long transporting
pipes etc.
2.the least flow resistance,small volume and weight, which is convenient to
install.
3.the fixed ball used the pressure of spring and medium to press valve base on
valve body to airproof, so the operation moment is smaller,is is applied in high
pressure and big-caliber valves. >>

1) Compact configuration, tiny bulk, light and operate skillfully and
conveniently.2) It adopt three dimensional eccentric elasticity or multiple
layers hard sealing configuration, the hermetical capability can reach to zero
leakage.3) This kind of valve with no flange, which makes pipe elegantly and
binding up conveniently.4) It have characteristic of high temperature
resistant, high pressure resistant, antisepsis, wearable, etc. >>
