Centric butterfly valve with loose liner and bare shaft - Lug for wastewater treatment and HVAC to max. 90° C

AVK centric butterfly valves with loose liner are available in wafer, lug and U-section design with a wide standard range of actuators. The butterfly valves are designed with square driven anti-blowout shaft and slim disc of Rilsan coated ductile iron with smooth edges resulting in low torques.

Variant 820/10-033
Connection: Lug type
Material: Ductile iron body/GGG disc, Rilsan coated
DN: DN25 - DN600
PN: PN 16
Closing direction: Clockwise to Close

Features

  • Ductile iron with long neck for insulation
  • Loose liner of EPDM with integrated gasket faces and "saw profile" for optimum grip in body
  • Square driven anti-blowout shaft in one-piece design up to DN 400, and from DN 450 with key and keyway in two-piece stub design with two self-lubricating bearings
  • Slim disc of Rilsan coated (200 μ) ductile iron with smooth edges reducing the friction between liner and disc
  • Low operating torques allowing use of cost-effective actuators
  • According to PED 2014/68/EC appendix 1
  • Other flange drillings on request
