Application 1
For standard use without media flow

Application 2
For complicated media requirements, such as acids and dry service

Product Advantages

Ideal for use in vacuum
due to the vulcanized seat ring on a metal ring

Excellent control behaviour without hysteresis
with firm, play-free disc/stem connection and centric valve disc

Valve design cavity-free
makes simple sterile cleaning possible and choice of body material independent from the medium

Long service life
seals tightly at full differential pressure even with very high switching cycles.

Excellent bubble-tightness
Multi-functional seat-ring easily exchangeable, maintenance-free, long service life, reliable sealing in the seat, to the flanges and at the stem bore; safe locking in dovetail, embedded in the body without edge projection to the flange surface

Absolutely maintenance-free seal system
the bearing with O-ring prevents foreign substances from penetrating from the outside

Universal range of application
for almost all media, from use with acids to the sensitive food and pharmaceutical industries

Economic and easy assembly of all actuator types
the standard top flange according to DIN/ISO 5211 makes it possible to mount all common actuator types

Application Range

Industries and applications

  • Water / sewage
