Brand: DeZURIK
DeZURIK rotary diaphragm actuators are designed specifically for use on quarter-turn valves.
The actuators are designed for on-off or modulating service in either a fail-open or fail-closed mode.

The DR-40B actuator features enclosed construction, smooth throttling control and accuracy, externally adjustable stops and external position indication.
The spring cartridge is caged at the factory for increased safety and optional OSHA lockout devices are available.
