Non-Lubricated Plug Valve

Alis Valves is a leading manufacturer of Non-Lubricated Plug Valves designed for reliable and maintenance-free flow control in corrosive and clean service applications. Unlike lubricated types, these valves use a PTFE or polymer sleeve/lining to provide sealing and reduce friction, eliminating the need for external lubrication. This design ensures bubble-tight shut-off, smooth operation, and long service life even in aggressive chemical environments.
