The compact actuator reduces valve/actuator envelope dimensions to provide greater valve installation versatility for both skids and tight processing lines where space is at a premium. The actuator can be installed on rotary-shaft valve bodies for throttling or on-off applications. The actuator linkage features a clamped shaft lever and a single pivot point to reduce lost motion between the actuator and the valve. The result is 0.5% or less typical variability for a rotary control valve assembly. In addition, the compact actuator delivers several operations and maintenance advantages. It has an inherent failsafe position on loss of operating air. In contrast to piston style actuators that rely on O-ring seals, the double-sided diaphragm in the 2052 provides a longer service life. The actuator offers a unique, nested spring design that requires no bench set, simplifying the actuator selection process. Powder paint coating is standard and offers an excellent corrosion-resistant finish on all external steel and cast iron parts. The actuator is available in three sizes, from ½- to 1-1/2-inch.
