Contact
Pham Trung
Technical Manager
For drinking water and neutral liquids up to max. 90°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.
