ISA 96.06.01

Abstract

This standard provides requirements for the specification of self contained electro-hydraulic linear and rotary valve actuators, both double acting and single acting, used for on-off/isolating, positioning and continuous modulating duties. Self contained electro-hydraulic actuation is defined as any actuator which: <br>a) Utilizes hydraulic fluid as the driving medium <br>b) Requires only electric power and a control signal to operate <br>c) Has its own dedicated electronic controller <br>d) Has its own dedicated hydraulic power unit (HPU) <br>This standard does not apply to electro-hydraulic, multi-turn rotary actuators which drive a threaded stem. <br>Other requirements, or conditions of use, different from those indicated in this standard, shall be subject to negotiations between purchaser and the manufacturer/supplier, prior to order. <br><strong>Purpose</strong> <br>The purpose of this standard is to establish minimum design requirements and to assist the user in specifying electro-hydraulic valve actuators.
