Pneumatic O-type SIL2 emergency shut-off valve

Introduction and Application

This ME650 series of soft-sealed Boating ball valves has simple structure. The sphere is a boating structure, relying on a single force of the medium acting on the sphere, bringing the sphere closer to the seat on one side. The sealing function is realized by extrusion seat, which is mainly used in low pressure cut-off applications. This series of valves is ideal for use as piping switches. It has the characteristics of compact structure, light weight, high circulation ability, strong cut-off performance and long service life. It is the best choice for working conditions such as steam, hydrocarbons and corrosive media.
