DeZURIK Rotary Diaphragm Actuators

DeZURIK rotary diaphragm actuators are designed for use on quarter-turn valves, for on-off or modulating control in fail-open or fail-closed mode. Fail-safe operation can be easily changed in the field without any additional parts.

Rotary diaphragm actuator design features a sealed and gasketed design to protect against grit, moisture and corrosive contaminants.

The popular DR-40B stainless steel design offers resistance against corrosion in a variety of industrial environments. DR-55, DR-85, DR-145A and DR-250A epoxy-coated cast iron and steel construction actuator models are available for larger rotary control valves.
