FKOF/FM - Butterfly valve DN 40:400

Butterfly valve with bare shaft.

The FK is a butterfly valve for shutting off or regulating flow, with structural characteristics that make it ideal for industrial applications requiring high performance and longterm reliability. This valve is also equipped with the customisable Labelling System.

Main features:

• Ergonomic handle in HIPVC equipped with locking and unlocking device, release, quick operation and graduated adjustment in 10 intermediate positions (DN 40÷200). The operating range, starting from the first few degrees of valve opening, also guarantees extremely low pressure drops
• Customisable Labelling System: integrated module in the handle, made of a transparent protection plug and a customisable tag holder using the LSE set (available as an accessory). The customisation lets you identify the valve on the system according to specific needs
• STAINLESS steel square section stem completely isolated from the fluid complying with standard ISO 5211:
  • DN 40÷65: 11 mm
  • DN 80÷100: 14 mm
  • DN 125÷150: 17 mm
  • DN 200: 22 mm
  • DN 250÷400: 27 mm
• Body in polypropylene based compound reinforced with fibreglass (PP-GR) resistant to UV rays and characterised by high mechanical strength
• Drilling pattern using oval slots that allow coupling to flanges according to numerous international standards. The special self-centring inserts in ABS supplied for DN 40÷200 guarantee the correct axial alignment of the valve during installation. For DN 250÷400 valves, the drilling pattern for the selfcentring system is of the traditional type according to DIN and ANSI standards
• Interchangeable liner with the dual function of forming a hydraulic seal and isolating the body from the fluid
