By the crank and the brake control tower or pool float liquid level, maintenance is simple, flexible and durable, accurate level control floating ball valve and high pressure water without interference and the opening and closing close watertight.
Is a sphere without support shaft, the ball was holding one of two seats was "floating" status, which is mainly used for cutting pipe, distribution and change the flow direction. Main features of floating ball valve seat seal design, reliable sealing valve closure lever down, fire-static, automatic locking devices, pressure relief and structural characteristics.
The main structure of the floating ball valve features:
1 valve with open and close position indicator;
2 locking devices;
3 stem anti-fly structure;
4 anti-static devices;
5 fire structure;
6 unique seat sealing structure;
7 in the flange (body and left body junction) structure without leakage.
Floating ball valve according to different requirements, based on the shell material is divided into: general carbon steel (WCB & A105); stainless steel (304,316); low temperature steel series (LCB, LCC); sulfur series.
Floating ball valve for: chemical, petroleum, natural gas, metallurgy, etc., and hydrogen sulfide media, impurities and corrosion of the long distance gas pipelines.
