Coatings

Butt ends
  • welded integration into the pipeline
  • no risk of leakage
  • high safety factor
Heating jacket and heated shaft
  • continuous heating of the housing jacket and the shaft by heating medium (e.g. steam or process gas)
  • avoids cooling of the medium and thus hardening in the flow-through
Mechanical stroke limitation / limit stop
  • ensures optimum positioning of the disc in the housing seat
  • reduces friction between the disc seal and the seat ring
  • thus reduces wear on the damper seal
Outer bearings
  • Use especially with higher media temperatures and media containing solids
  • minimises heat transfer from the medium to the bearings
  • prevents the medium from penetrating into the shaft bearings
Flow protection
  • movable, spring-loaded plate protects the disc seal in the inflow area from abrasion
  • ideal for gaseous media with high flow velocities and high solids content
Coatings

Hard rubber coating:

  • low-cost alternative to the stainless steel version
  • Inner lining of the valve and valve disc with hard rubber coating based on polyisoprene rubber (IR) and styrene butadiene rubber (SBR)

Hard coating:

  • increases resistance to abrasion and corrosion.
  • application especially at high temperatures and for heavily stressed surfaces
