Design Feature
Upstream Seal Two-way Valve,Fire-Safe Design API 607/API 6FA
Stem and Seat Emergency Sealing
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.
