The DS/DMS Series is a direct-mount, spring return line of electric actuators that operates on 24/120/230 VAC or 24 VDC power and is available for use with on/off, floating, proportional, or resistive controllers. These bi-directional actuators do not require a damper linkage, and are easily installed on a round shaft up to 3/4 in. (19 mm) diameter or a square shaft up to 1/2 in. (13 mm). They can also be mounted to butterfly and ball valves using one of the Bray Valve Linkage Kits.
The DS/DMS Series delivers up to 177 lb-in (20 Nm) of torque. The angle of rotation is mechanically adjustable from 30 to 90°. Optional auxiliary switches are available to indicate end-stop position or to perform switching functions at any angle within the selected rotation range. Position feedback is available through switches, a potentiometer, or a 0 (2) to 10 VDC signal.
