Pressure Balanced Lubricated Plug Valve
Pressure balance lubricated plug valves are metal seated valves providing a tight shut off ( 0 leakage ) sealing, valves shall be regularly lubricated along with their operation by injection of suitable grease. Thanks to the absence of any body cavity and as well as a simple & tough design, they are highly recommended for any critical “Full P” operation and for handling any media with an high % of solids contents, further more they provide an excellent resistance to abrasion, they are free from routine maintenance, providing a long service life.
PTFE Sleeved Plug Valves
The PTFE sleeve serves as the seat for the valve plug thus eliminating contact of two metal surfaces. Turning effort is low and galling is avoided. The design also permits the use of any body/plug material combination. Positive shut-off is ensured and the valves are free from regular maintenance.
