Bradford Dixon RP-BA-101-SR Pneumatic Actuator

Bradford Dixon RP-BA-101-SR is a spring-return rack-and-pinion pneumatic actuator designed to rotate 4-inch sanitary ball valves through a precise 90-degree stroke, enabling fast and repeatable on/off control in industrial and sanitary process lines. The SR suffix identifies its spring-return operation, providing fail-safe closure if pneumatic pressure is lost and ensuring the valve returns to a safe position without external power. Built around a rugged rack-and-pinion mechanism, the actuator converts compressed air into smooth, dependable valve movement and is intended for use with Dixon sanitary ball-valve assemblies in environments where hygienic design and cleanability are essential. Dixon's actuation references list RP-BA-101-SR for 4-inch valve sizes, confirming its sizing and direct compatibility with Dixon sanitary valve hardware and related actuation components. This combination delivers straightforward installation on compatible Dixon ball-valve installations and supports reliable cycle performance in demanding plant settings, including sanitary process environments where hygiene and cleanability are critical.
