Lined Butterfly valves provide for resistance to permeation which leads to an extension of product life and greater operator safety as it does not permit atmospheric leakage.
Low torque results in several benefits such as smaller operators taking up less space, ease of operation and cost savings with less expensive automation packages.
An added benefit is atmospheric sealing integrity and no manual adjustment over the life of the valve.
