مشخصات:
Cast iron butterfly valve for mounting between flanges, “Wafer” type
1. EN ISO 5211 top mounting
Easy coupling with every kind of drives.
2. Three guiding bushings on the shaft
It grants a perfect alignment of the shaft on the body and prevents oscillations 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 for 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
Wide range of LINER materials
Various applications possibility
