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
