Features & Benefits


Low Friction Regulating API609 Butterfly Valve Corrosion Resistant 0


1 EN ISO 5211 top mounting Easy coupling with every king of drives.
2 Three guiding bushings on the shaft It grants a perfect alignment of the shaft on the body and prevents oscillation even with high pressure
Less friction between the shaft and body.
3 Vulcanized liner on rigid ring Less deformation of the liner
Easy assembly/disassembly of the liner of maintenance
No deformation of the liner between the flanges during assembly.
Greater dimensional accuracy during the injection/molding.
4   Shaft in 2 pieces without fixing components Easy assembly/ disassembly of the disc for maintenance
Higher Kv thanks to the central section of the disk thinner than a valve with a single shaft
5 Lapped surface of the disc’s circumference Better tightness and less wear of the liner
Lower torque due to less friction between the disc and liner.




  1. Face to face as per EN 558 series 20
  2. Integral sealing which avoids any contact between fluid and valve body
  3. Sealing design allowing perfect adherence to the valve body and perfect tightness to the flanges, without additional parts, clamping between flanges does not influence the torque of the valve.
  4. Lapped disc edges that allows better tightness, reduced torque and low wear of the liner
  5. Bushes to support the shaft.
  6. Valve neck with top work as per EN ISO 5211 for easy connections with all different types of actuators.
  7. All components properly treated against corrosion
