These valves are specially designed to work well in places with no air, called vacuum environments. They're built to handle the challenges of these conditions and work reliably without losing effectiveness. This makes them a good choice for situations where keeping things airtight is really important.
When picking the right materials for butterfly valves used in marine applications, it's important to think about what's needed for the job. KA-series butterfly valves have lots of material options for body, disc and the rubber seats. This helps them work well and last a long time.
The diverse range of material options guarantees that the KI-series can be tailored to address the distinct requirements of various applications within the maritime industry.
A very wide range of elastomers allows the best combination of materials depending on the application. The body rubber seat is replaceable for DN 40/150. DN 200/800 is vulcanized an not replaceable.

Outward sealing is guaranteed by a double packing at both the top and bottom of the shaft.
The adjustable lower support prevents axial movement of the shaft-disc unit. Furthermore, when the valve is assembled with a vertical shaft, the disc does not exert pressure on the seat, leading to a longer valve lifespan.
All GHIBSON Butterfly Valves are equipped with an anti-blowout system for the shafts in compliance with EN736 and API609 standards.
Its shape ensures the best anchoring to the body, even in challenging applications. Valves larger than DN300 feature a specially designed shaft-disc connection that ensures a strong coupling while avoiding clearances. This design provides higher shaft tensile capacity due to a section considerably larger than the classic square section.
For valves larger than DN500, this solution enables robust fastening without clearances and easy maintenance.
