BUTTERFLY VALVE, DOUBLE ECCENTRIC, SHORT, PN10/16

IP67 gearbox w. handwheel/pos. ind., intgr. seat, EP coated seal ret. ring, SS shaft, A2 fasteners, 250µm EP coating

Double eccentric butterfly valve for neutral liquids like drinking water, filtered raw water and filtered wastewater to max 70°C

AVK series 756 double eccentric butterfly valves with tilted disc are designed for easy operation and long service life. The disc seal is made of AVK's drinking water approved EPDM rubber featuring an excellent compression set and ability to regain the original shape. The high quality epoxy coating and fully encapsulated shaft/disc connection ensure optimal corrosion protection and durability.

Variant 756/H18-001
Connection: Flanged
Material: Ductile iron
DN: DN400 - DN1600
PN: PN 16
Closing direction: Clockwise to Close

Features

  • Machined and epoxy coated ductile iron seat integrated in the body
  • Rotork gearbox, IP67, with handwheel and position indicator
  • Double eccentric design releases seal compression after only few degrees of opening resulting in low operating torque
  • Disc firmly fixed to the shaft to prevent fluttering and a slight tilt allows for precise adjustment of the closed position
  • All threaded connections are sealed with O-rings for protection against medium and environment
  • CSB self-lubricating radial- and thrust bearings
  • Replaceable shaft seals with two EPDM O-rings
  • Shaft fully encapsulated in disc and sealed by gasket and O-ring
  • Coating DN≤1600: Blue RAL 5017 FBE to DIN 3476, GSK and approved by WRAS-DVGW/W270/UBA, 250µm. Coating DN≥1800: 2-pack EP, WRAS approved, RAL5017 externally and ribbon blue or cream white internally, 250µm
  • Drinking water approved by DVGW (DN≤1200) and WRAS (DN200-1200)
