The 2052 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 Fisher rotary control valve assembly. Other 2052 features include 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, says the vendor. The actuator is available in three sizes, accommodating shaft sizes 12.7mm to 38.1mm (1/2 to 1-1/2 inch).
