Plug Valves – KPD-PVF
A sleeved plug valve is a non-lubricated valve that achieves sealing through the use of a compressible sleeve as a sealing member.
The inert PTFE sleeve completely surrounds the plug and provides a large, circumferential sealing surface from port to port.
There is no contact surface so the medium cannot cause damage.
PTFE has a self-lubricating effect and therefore requires no maintenance.
Sleeved plug valves are used for on/off and throttling service in demanding process applications.
