Quarter-turn valve actuator DAPS

pneumatic90°Scotch yoke

The compact and robust quarter turn actuator DAPS with lever-rocker kinematics is specially designed to meet the requirements of the process industry. • High breakaway torques • Flange hole pattern to ISO 5211 • Mounting hole pattern to VDI/VDE 3845 • Available with handwheel as a manual emergency override • Corrosion-resistant variant made from stainless steel • As per EU explosion protection directive (ATEX) • With safety functions The quarter turn actuators DAPS arespecially tailored to the requirementsof the process industry. The torque isgenerated via a scotch yoke mechanism, which helps to overcome thevalve's high breakaway torques.Given their robustness and graduatedtorques, the quarter turn actuatorsDAPS are predominantly used to control valves through which various media flow and whose rotation angle islimited to 90°, e.g. ball valves andbutterfly valves. • Compact design • Torque characteristics adapted to process valves • The single-acting actuator has half the torque of the double-acting actuator for the same housing size • Low wear thanks to the simple and robust mechanical system • Adjustable swivel angle • Selected types in accordance with the ATEX directive for potentially explosive atmospheres
