Non Lubricated Plug Valve

Speciality valve is the leading Non Lubricated Plug Valve Manufacturer in India. Non Lubricated plug valves are robust in construction and easy to maintain inline. It has a sleeve or liner installed in the cavity. The narrow plug wedges the sleeve against the plug body. The non-metallic sleeved decreases friction during operation.

These valves are sleeved quarter-turn plugs that achieve sealing using a compressible sleeve as a sealing member. Nonlubricated plug valves are bi-directional flow, simple actuation, lightweight, compact design, and multiport configurations all of which improve the design system. It is limited by the temperature and chemical compatibility of non-metallic materials.
