For HVAC and other high temperature applications up to max. 130°C.

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

Variant 820/20-024
Connection: U-shaped type valve
Material: Ductile iron body/1.4408 disc
DN: DN150 - DN1600
PN: PN10/16
Closing direction: Clockwise to Close

Features

  • Ductile iron body with long neck for insulation
  • Loose liner of EPDM for high temperatures 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 acid-resistant stainless steel with machined and polished edges reducing the friction between liner and disc
  • Low operating torques allowing use of cost-effective actuators
  • 200μ epoxy coating up to DN 400, 250μ polyurethane from DN 450
