Technova Butterfly Valves

Main Features:

  • Heavy-duty, compact construction
  • maintenance-free
  • Bubble-tight shut-off throughout the full pressure and temperature range
  • wide selection of high-quality liner and disc materials for economical valve performance
  • Unique shaft sealing arrangement assures maintenance-free operation at automated processes and high operating prerssures, with optimized and reinforced liner shape
  • One-piece disk/shaft for hysteresis-free flow control, with polished sealing surface, leading to low torque values
  • Wide and chambered flange sealing surface does not require additional flange gaskets
  • Flange drilling according to DIN PN10/16 resp. ANSI 150lbs for installation into existing piping systems

Typcial Service Applications:

  • Chemical CPI
  • Petro-Chemical
  • Bio-Technical
  • Pharmaceutical Industry

  • Chlor Alkali
  • Water Treatment
  • Detergents, Oils and Fatty Acids

Technical Data:

  • Nominal Sizes: DN25 - DN1000 respectively 1" - 42"
  • Flanges according to DIN PN10/16 resp. ANSI 150lbs
  • F/F acc. to EN 558-1 range 20 respectively ASME B15.10
  • Bodies: Cast steel ASTM A216 WCB, CF-8M, ISO flange
  • Liners: PTFE, PTFE-AS(conductive), UHMWPE
  • Discs: PFA, PFA-AS, PVDF- or ETFE-encapsulated, solid made of SS Duplex, Titanium Gr.2, Hastelloy
  • Elastomer backings: VMQ (Silicone), FPM (Viton), EPDM

Operating Conditions:

(depending on material selection)
  • Pressure 1mbar (0.14psi) up to 16 bar (232 psi)
  • Temperature -40C (-40F) up to +220C (+428F)

Dynamic Sealing System (standard):

  • Shaft sealing Pre-loaded, dynamic shaft sealing arrangement
  • the pressure ring transfers the bellevill-spring action and elastomer compression force onto liner and disc hub, providing a bubble-tight shaft sealing mechanism for upper and lower section.
  • Elastomer Backings provide a resilient and uniform pressure onto sealing surface for positive tight shut-off, available in various qualities
  • One-piece disc/shaft, SS Duplex (1.4462) cores with encapsulations made of PFA, PFA-AS, PVDF, ETFE or solid discs made of SS Duplex, Titanium Gr.2, Hastelloy C etc.

Testing / Marking:

  • Pressure and tightness testing acc. to prEN 12266-1, leakage rate A, and sparking at 35 kV to assure lining integrity. Marking on valves on body and name plate according to EN 19.
  • Material respectively test certificate according EN 10204-3.1B
