The unique 360-degree metal lip protection fixed card ensures there are no cavities for medium accumulation. The metal lip in the rotary plug provides a self-cleaning effect, making the valve suitable for sticky or scaling-prone conditions. It supports two-way flow and offers convenient installation. Sleeve-type soft-sealing plug valves are commonly used in corrosive, highly toxic, and hazardous media, as well as in environments where leakage is strictly prohibited or where the valve material must not contaminate the medium. The body material can be carbon steel, alloy steel, or stainless steel, depending on the working medium.
