Bonded liners

The Alfa Europe bonded liner butterfly valves are produced with latest design technology, including vulcanized rubber liner by injection moulding.


The Alfa Europe Bonded liner concept ensures that the liner cannot move around as a result of which;
• No tearing and distortion of the liner
• Very low wear of the seat
• Reliable low torque figures
• Exceptionally long seat life up to 3 x longer than replaceable liner valves
• Permanent dry lubrication shaft design
• Uniform sealing, bi-directional flow
• Low torque due to one shaft design
