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).
