Extended life span
This butterfly valve has a unique wave line rubber seat and a special disc
shape, enhancing the life span of the valve and sealing.
Reduced torque
Due to the unique wave line rubber seat and disc shape the butterfly valve
has a low torque.
One of a kind
It is the only butterfly valve in the world constructed with a bushing inside the
disc - resulting in lower torque, lower friction, 100% tight shut-off function
and a very long service.
Seat construction
On the Wafer type the seat is vulcanized onto a phenol back-up ring. On the
Lug type and the double flanged type the seat is vulcanized onto the body.
