The Model DFR can accept a splined shaft or square stub, making for easy automation of valves, louvers, dampers or any other quarter turn application. A CNC machined steel lever offers a higher factor of safety than a cast steel lever which makes DFR actuators stronger than most competitors. The rigid structure is also a stable base for accurate and repeatable performance.
The Model DFN is a bracket-mounted, direct acting, spring and diaphragm actuator. Common applications include operation of butterfly valves, chokes, and louvers. The steel welded design provides necessary stability and reliability under extreme working conditions.
The DFC and DFO Series linear output actuator's large diaphragm area allows for low-pressure operation, and the spring provides fail safe positioning of a control valve on loss of pneumatic supply. Model DFC actuators are fail closed and Model DFO actuators are fail open.
