ISA 96.02.01 PDF

This standard covers the development of specifications, minimum design requirements, and sizing criteria for electric actuators.

Electric actuators shall be self-contained assemblies comprising an electric motor, reduction gearing, position sensing and limiting mechanisms, torque sensing and limiting mechanisms, handwheel for manual override, and a motor control package.

This standard is not intended to address the range of compact electric actuators rated less than 5.65 Nm (50 in-lbs), and it is not intended for electrically powered actuators that use hydraulic fluid for power transmission (refer to ANSI/ISA-96.06.01).

Purpose

The purpose of this standard is to provide a guide to assist the user in specifying electric valve actuators.
