Plug Valve cross-section |
As detailed in the application photograph, Plug Valves are used as
compact, shut-off valves in a range of production equipment downstream
of the production tree. Plug valves are designed to operate with a
lubricant / sealant.
When the lubricant is applied to the valve, it is distributed between
the seating faces of the valve body and plug. The lubricant provides
an integral sealing and corrosion preventative film. As the plug is
covered by the lubricant over all surfaces, a smooth, controlled
actuation is achieved over extended maintenance periods.
Valve Lubricant 601 is used for the lubrication and sealing of Plug
Valves. 601 has been field proven to remain cohesive within the plug
valve whilst providing the necessary sealing.
This is unlike other
sealants which may harden, resulting in leakage and exceptionally high
actuation torques that can damage the valve stem.
The use of 601 in plug valves has allowed operators to standardise on
one lubricant product on all wellhead and downstream
flow control with both gate and plug valves installed
