Trunnion Mounted Ball Valve Content

Design Feature 

Upstream Seal Two-way Valve

Have two seats on both sides. Each seat has springs loaded and make seat insert contact the ball surface for sealing.

Therefore this type of valve is bi-directional sealing and Installation direction is not restricted.

Fire-Safe Design API 607/API 6FA

In case of accidental fire or abnormal heating that softens and burns the non-metallic valve seat, it is specially tested.

The broad-seat supported metal sealing surface can prevent internal leakage under the action of spring load.Meanwhile,

in the middle flange, the upper and lower parts of the adjusting stem will form metal surface contact, which can also

prevent upper and external leakage.

Stem and Seat Emergency Sealant Injection

The seat ring and the valve stem have a special grease injection valve. In case of the leakage,

the grease will be injected to the valve ball surface and stem room to create a temporary sealing.

Double Block and Bleed 

The trapped cavity pressure can bleed out by vent fitting or drain plug when the valve is in

fully open or fully closed position. The fluid is intercepted by seats of up and down stream

side. So the stem packing or O-ring may be replaced under working pressure. Each seat works

independently assuring tight seal against ball on both upstream and downstream side.
