Features
- Equipped with various disc materials and can be used in various flow types and different applications with the EPDM, NBR and VITON seat options.
- Compared to other valve types, with its compact dimensions offers the advantages of lightweight, easy installation and cost effectiveness.
- Head loss is at minimum level through the double shaft design of FAF Valve.
- The inner and outer surfaces of valve body are coated with electrostatic fusion bonded epoxy (FBE) / oven baked powder epoxy coating. Smooth operation and longer life is maintained in tough conditions.
- Higher coating thicknesses can be applied upon request.
- Up to DN 300 (inclusive) sizes are supplied with hand lever as default DN 350 (inclusive) and above are supplied with gear box as default.
