STRUCTURAL FEATURES

1.Special Seat Design
The floating ball valve adopts the design of flexible seal ring structure. When the medium  pressure is lower, the contact area of seal ring and ball is smaller. so higher sealing ratio is formed at the place where the seal ring and ball contact to ensure reliable sealing. When the medium pressure is higher, the contact area of seal and ball becomes bigger along with the elastic deformation of seal ring, so the seal ring can endure higher medium thrust without being damaged.

2.Fireproof Structure Design
In case of fire during the use of valve, the seat ring made of PTFE or other non-metal materials will be decomposed or damaged under high temperature and cause higher leakage. The fireproof seal ring is set between ball and seat so that after the valve seat is burnt, the medium will push the ball rapidly towards the downstream metal seal ring to form the auxiliary metal to metal sealing structure, which can effectively control valve leakage. In addition, the middle flange sealing gasket is made of metal wound gasket, which can ensure sealing even under high temperature. The fireproof structure design of floating ball valve conforms to requirements in API 607,API 6FA,BS 6755 and other standards.

3.Anti-static Structure
The ball valve is provided with anti-static structure that between ball&stem and stem&body are assembly by a spring&a SS ball,which ensure all metal parts are grounding.

4.Anti-static Structure

The handle stop with locking hole is prevent continually open or close the valve when the valve is in completely open or closed position.Morever,the valve can be locked when don’t need.
