Wafer Pattern Butterfly Valves
A universally applicable wafer type valve acc. to EN 593.
The large variety of basic materials allows applications in different industries.
Aluminium version. Available sizes: DN 50 - DN 400
Features:
- Absolutely tight sealing with flow in either direction
- The valve body and disc are accurately machined which results in low operating torque and long service life and reliability
- Triple shaft bearings prevents shaft deflection and guarantees optimum guidance even after many years of operational service
- Four flange mounting holes ensure correct valve location when installing
- Single flange mounting is possible (please request details)
- Can be installed in any desired position
- Maintenance-free
- Can be disassembled, material-specific recycling possible
General applications:
- Chemical and petrochemical industries
- Water and wastewater technology
- Pneumatic materials handling technology
- Shipbuilding
- Power generation industry
- Food industry
- Civil engineering
- For paint and lacquers, a silicon-free version is available
