Adoption of differential pressure cancellation mechanism
Easy upsizing of the seal opening (field-proven from G5 to G10)
Improvement in reliability of seal performance
Because no inclination operation of the valve plate is required, sealing operation stabilizes, improving reliability.
Light-weight (The atmosphere-side mechanism is compact.)
Reduction of drive air consumption (50% reduced from our conventional products)
Reduction of trouble risks by O-ring adhesion
The absence of frictional parts prevents the formation of particles, enabling clean operations at high levels.
Easy maintenance (easy attachment/detachment of the valve plate)
