Butterfly valve is of centric design and compact face-to-face dimension being used in cases where lug or wafer type valves are needed. The sophisticated design guarantees perfect leak tightness and a long service life:

• Replaceable elastomer body seat ring, safe against mechanical and hydrody namical strains
• Anchoring of the seat ring in the body to avoid any displacements when retracting the valve disc
• Positive and frictional disc /shaft connection for functionally safe connection without fluttering.
• Maintenance-free, self-lubricating and PTFE coated bearing bushes, triple bearing shaft bearing assembly
