Applications
Split Body Trunnion Mounted Ball Valves are mainly applied to natural gas, oil products, chemical engineering, metallurgy, city building, environment protection, pharmacy and food industries, among which the anti-sulfur series are used for long delivery pipes of natural gas that contains hydrogen sulfide medium, a lot of impurity and corrosive substances.

Design Features
Seat Design
The standard seat design is primary soft seal, and secondary metal to metal seal. Seat insert is designed as pressure-in type which is easy for maintenance. (FIG.1)

Blow-Out Proof Stem
The stem is made separately from the ball with integral T-type shoulder to be blow－out proof. It also functions as the backseat for assure stem sealing safety at all pressures. (FIG.2)

Anti-Static Device
When open and close the valve, the friction between the ball and the non-metal seat will be produce static charges. To avoid static sparkle, an anti-static device (spring loaded ball) is designed between the ball, stem and body, form an electrostatic channel and achieve the purpose of removing static electricity. Effectvely prevent the burning of flammable media due to static electricity. (FIG.3)

Fire Sate (Option)
Floating ball valves' fire safe confirm to API 607 and API 6FA Standards.
When non-metal material seats are broken or destroyed by fire, ball valve changes to metal to metal auxiliary seal structure, which will prevent effectively internal leakage or external leakage. (FIG.4)

Locking device
Lever operated ball valve with locking device. Facility for mounting a locking device for prevention of accidental valve operation in provided. (FIG.5)

Gear operated ball valve with the locking device is available upon request.
