The NIBCO NDA4F04 is a double-acting rack-and-pinion pneumatic actuator for compatible quarter-turn valve applications. It delivers 337 in-lb of output torque at 80 PSI and uses an ISO 5211 F04 mounting interface for compatible ball, butterfly, plug, and damper assemblies.
An anodized extruded-aluminum body, epoxy-coated end caps, solid steel shaft, Buna O-ring seals, NAMUR accessory mounting, and star-shaped drive support durable operation. Port A drives counterclockwise opening, while Port B drives clockwise closing.
This listing is intended for compatible NIBCO 2 through 4 in. valve configurations. Confirm the valve torque requirement and mounting interface before selection.
