fitur-fitur

  • 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
  • Disc seal profile and rubber quality ensure low closing torque
  • All rubber parts drinking water approved by multiple institutes
  • Fasteners in stainless steel, A2
  • Stainless steel shaft and seal retainer ring
  • Machined and epoxy coated ductile iron seat integrated in the body
  • All threaded connections are sealed with O-rings for protection against medium and environment
  • Radial bearings in self-lubricating PTFE/bronze composite
  • Shaft ends fitted with an end cover that keeps the shaft in position against system pressure and seals the disc interior against corrosion
  • Replaceable shaft seals with two EPDM O-rings; gaskets to the exterior in hydrocarbon resistant NBR
  • Coated with blue RAL 5017 FBE to DIN 3476, GSK and approved by WRAS-DVGW/W270/UBA, 250µm
  • Drinking water approved by DVGW and WRAS
