The “GALACTIC” butterfly valve is specially recommended for heavy duty applications where a high performance is required.

Valve design features:

  • Quality management system according to ISO 9001:2015.
  • Body encircling type seat made of virgin Poly Tetra Fluoro Ethylene “PTFE”, isostatically moulded of 3mm thickness, and makes this valve highly suited for chemical applications.
  • Disc encapsulated with PFA and UHMWPE, 3 mm thick, mechanically fastened and isostatically moulded.
  • The one piece investment cast stainless steel slim disc and shaft offers a very high “Cv” or “Kv” rating, which minimizes obstructions to the flow (low pressure drop).
  • Shaft PFA or UHMWPE coated in areas in contact with the liner, ensures complete stem isolation from the fluid.
  • The contact between the PTFE liner and the encapsulated PFA disc causes a minimal friction coefficient and therefore minimum wear and, consequently, a constant and low torque value.
  • Only the disc and the liner are into contact with the fluid.
  • PTFE coated self-lubricating bearings.
  • Centring holes in Wafer body for the right alignment with flanges during installation.
  • Body design permitting to place heat insulation.
  • Top flange to ISO-5211 to fit any type of standardized actuator.
  • Stainless steel bolting to fix both parts of the body.
  • Maintenance free.
  • Full trazability of components.
  • Manufactured according to latest standards and applicable regulations.
  • Possibility of marking to Pressure Equipment Directive 2014/68/EU, European Directive ATEX 2014/34/EU concerning equipments and protective systems intended for use in potentially explosive atmospheres, and certificates to work with drinking water for human consumption.
