gearbox with adjustable endstops and
mechanical position indicator on the gearbox cover
Gearbox with raised protection for buried
application available as an option
Double-eccentricity
On the basis of the double-eccentric bearing of the valve disk
the profile seal lifts off from the seat when starting the rotary
movement. Thus no shear stresses between seat and profile
seal arise (ecc.1).
The bearing of the shaft stubs behind the seal section enables
the use of an endless seal on the disk which provides a perfect
sealing and functionality (ecc.2).
Exz.1
• Best possible closing of the sealing into the body seat
• Reduced operating force with perfect sealing function
• Long life due to low wear of the sealing ring
• Relief of the sealing ring in open position

Drive shaft connected with the disk
accurately by means of double taper pin.
Due to generously dimensioned
bearings the shafts are not in contact
with the medium, all transitional areas
safely sealed by means of O-rings.

Dynamic sealing of the drive shaft
by means of O-rings in double safety
design, bearing bushings of selflubricating Bronze guarantees a safe
and long life time.
Endless closure sealing of loadable
elastomer in special T-profile attached
to the disk by means of a one-piece
retaining ring, exact pre-load and
securing by means of fixing bolts and
counter pins guarantee safe operational
leak-tightness.
