The DSA-Series single-acting spring diaphragm actuators by Master Flo are engineered for robust, long-lasting performance. These actuators feature a generous diaphragm area, allowing operation at low pneumatic pressures, while an opposing spring ensures fail-closed (standard) or optional fail-open action. You can mount various positioners and instruments directly to the actuator for added flexibility.
