Company Detail
Design ideas:
 The valves in the past can be fall into globe valve, butterfly valve, plate valve etc. A brand-new globe valve,  the handle  is very  tough because of its tightly joining. But after using two years or so, friction loss of the  valves would  lead to  dripping, weeping or leakage, the same as butterfly valve and plate valve, while, packless  valve can absolutely avoid  present difficulty of the valve.
 Design features:
 1.Adopting precision ceramics as valve board, using perforated ceramic boards and rotatable perforated ceramic  boards by rotating which to control the flowing of the water.
 2.The precision ceramics have been much fine grinded, therefore, the space between the two ceramic boards would  be vacuum suspending, and it does not get rubbed; what’ s more, the handle is good, the valve does not get  damaged.
