FKM

Gearbox operated Butterfly valve.

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÷300: 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.
