Double Off-Set Disc

Marck Valve Automation is Butterfly valve Double Off Set Disc Manufacturers in India. Double-offset valves feature have 2 offset stems that provide especially long life as a result of reduced contact between seats, discs, and valve, and are actually known as high performance butterfly valves.

A double offset butterfly valve is a high-performance valve where the stem is offset from the centerline of the disc and the centerline of the valve body. This “double offset” design creates a cam action, allowing the disc to lift away from the seat as it opens, significantly reducing friction, torque, and wear on the seat and disc. This design results in a tight, long-lasting seal and makes the valve suitable for a wider range of applications, including high-temperature and high-pressure services
