Features of Ghibsons Soft Seated Butterfly Valves
Special Shaft Double Packing - Outward Sealing
Outward sealing is guaranteed by a double packing at both the top and bottom of the shaft.
Detail of Lower Support - Adjustable Lower Support
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.
Ghibson Butterfly Valves - Anti-Blowout System for Shafts
All GHIBSON Butterfly Valves are equipped with an anti-blowout system for the shafts in compliance with EN736 and API609 standards.
Detail of Replaceable Body Seat - Shape Ensures Optimal Attachment
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.
Detail of Shaft-Disc Fastening - Strong Fastening for Valves over DN500
For valves larger than DN500, this solution enables robust fastening without clearances and easy maintenance.
