    Pneumatic Actuators - Double Acting or Spring Return
    The NIBCO® Series NDA/NSR pneumatic actuator features a patented spring design and a durable anodized extruded aluminum body. They are specifically designed for quarter-turn applications, including ball valves, butterfly valves, dampers and plug valves. NIBCO pneumatic actuators are manufactured in a wide range of output torques to fit the characteristics of the valve application. They are designed for either on-off duty, modulation or proportional control in industries ranging from chemical processing and pulp and paper, to petroleum refining, production industries, marine applications, and commercial construction applications. NIBCO® Series NDA/NSR pneumatic actuators offer exceptional starting and ending torque in a compact design. They consistently meet the demand for high torque, even in applications where the valve has been closed for an extended period. Engineered for a long, lubrication-free service life, NDA/NSR actuators combine O-rings and PTFE seals to create a durable, low-friction seal. Pneumatic accessories include three and four way solenoids, switch box with limit switches and beacon, positioners for air or electric signal throttling service and speed controls. Please refer to NIBCO technical data sheets, valve selection guides and catalog for engineering and installation information.
