This standard provides general requirements for the development of specifications for pneumatic rack and pinion actuators. This document applies to actuators with a maximum allowable operating pressure (MAOP) up to 145 psig with a compressed gas (e.g.@ instrument air). For the purpose of this document@ 0 degrees always refers to the valve in the closed position and 90 degrees generally refers to the valve being fully open. Purpose The purpose of this standard is to provide a guide to assist the user in specifying pneumatic rack and pinion actuators.
