Deye Trunnion mounted ball valves are built as standard in accordance with the design requirements of API 6D and, upon request, B16.34; both in two- and three-piece bolted construction.
Independent floating spring-loaded seat rings are always in contact with the ball to provide an effective tight seal at low differential pressures. At higher differential pressures, the upstream seat ring becomes pressure energized against the ball to ensure the seal, whilst the downstream seat remains spring loaded. The single sealing feature, standard on Trunnion mounted ball valves, is ideal for block and bleed service to API 6D.
The valve body cavity can be vented to atmosphere through a bleed valve and completely drained
by removing the drain plug with the ball in closed position, even when the line is pressurized. This feature also allows easy replacement of upper stem seal and the checking of the sealing of the seats while the valve is installed in the pipeline. All valves meet the antistatic requirements of BS 5351.and in compliance and certified to BS 6755 part 2 and API 607 IV Ed.
Mainly used in petroleum, petrochemical, chemical, metallurgy, electric power, water conservancy, urban construction, fire protection, machinery, coal and food industries
