Product Overview: 
 The floating ball valve full bore and shrink the diameter of two structural forms. Used to deliver the post even, easy to knot the residue on the media pipeline ball valves with full bore, to facilitate the adoption of the regular scraping wax purge. Wish to use the medium for transmission of gas or physical properties similar to water pipes reduced bore ball valve light for about 30% of its weight than a full bore ball valve, will help reduce the pipeline load and reduce costs. The ball valve is a corner for 90 ° rotation type valve sealing performance (full bore ball valve) flow coefficient crowd resistance coefficient is small, simple structure, long life, ease of maintenance. The products are widely used in chemical, petroleum, textile, electric power, food, pharmaceutical, refrigeration, paper industry, the system control. 
 Features and Benefits 
 ● floating ball switch position indicator: the body, ball and handle an assembly unit, to handle pipeline point to the direction of the valve is open, handle vertical pipeline direction valve is off; worm head with open / off instructions. 
 ● locking device design: In order to prevent incorrect operation of the switch, using the flat head and stem locking hole in the switch position is set to ensure that the valve is in the correct position. 
 ● anti-blow-oriented stem. Stem by the seal ring seal, even in the event of fire, burning filler stem protruding parts can also be in close contact with the sealing surface on the body, can be used effective to prevent leakage and stem from the valve body flip, fly out reduce accident losses. 

 ● Anti-static design: chrome-nickel stainless steel springs and ball to each other conductive ball, stem and body, and thus the release of static electricity generated by non-metallic valve seat and ball friction. 
 Unique seat design: floating ball valve double inclined plane flexible seal seat or V-groove elastic sealing seat structure design to ensure the reliability of the sealing surface, for low-voltage, ultra-low pressure or vacuum conditions with the ball valve The leaf spring loaded seating structure to ensure long-term reliable ball valve seal. , High temperature ball valve seat material could be a bit polystyrene or metal materials. Fire safety design, precise machining of the seat bearing surface inside a fire seal lip formed between the metal to metal seal when the fire valve burning, fire sealing lip and ball valve packing gaskets are resistant thermostat graphite materials to ensure that no leakage of the valve when the fire broke out. 


 ● valve in the flange connecting bolts using stud for ease of maintenance, demolition.
