Description

Lift-type plug valves are valves that, during opening and closing, first lift the plug away from the valve seat, then rotate it 90°, and finally lower it to compact and seal. They feature a full metal-to-metal seal (no soft seal or only an auxiliary one), solving the problems of high torque and easy abrasion of the sealing surface in traditional plug valves.

Features :

· Low opening and closing torque, frictionless rotation of the sealing surface, and long service life; Metal hard seal resistant to high temperature, high pressure, and media containing particles/erosion, and fireproof.
· Full bore, low pressure drop, and bidirectional sealing.
· Compact structure, with some models allowing for in-line replacement of the valve seat/plug.
