ISA 96.06.01 PDF

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:

a) Utilizes hydraulic fluid as the driving medium

b) Requires only electric power and a control signal to operate

c) Has its own dedicated electronic controller

d) Has its own dedicated hydraulic power unit (HPU)

This standard does not apply to electro-hydraulic, multi-turn rotary actuators which drive a threaded stem.

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.

Purpose

The purpose of this standard is to establish minimum design requirements and to assist the user in specifying electro-hydraulic valve actuators.
