MS670 Series Three-eccentric-hard-seal Butterfly Valve

MS670-PDF

The MS670 series triple offset hard sealing butterfly valve features a dual offset structure combined with an asymmetrical sealing surface design. This design ensures that the valve plate has no friction with the valve seat throughout its entire 0-90° travel range, eliminating wear and friction forces caused by rotation in control valves. It changes the traditional sealing method of rotary control valves that relies on grinding to achieve sealing, and instead uses a compression seal. The valve seat adopts a multi-layer structure, combining metal and special non-metal materials to form the sealing surface, which effectively ensures leak-tightness. This series of butterfly valves offers a long service life, excellent sealing performance, and can meet the requirements of high-temperature applications. It is suitable for regulating and cutting off most gases and liquids in industrial process control.
