through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

position between fully open and fully closed.
D Continuous modulating The electric actuator is required to continuously drive the valve to
any position between fully open and fully closed.
