Valve actuators shall mount directly to the bonnet
of the valve, and connect to the valve stem
without requiring adjustments, linkages, brackets
or adapters.
Direct coupled valve actuators shall be 24 Vac
power, available with floating or analog control
signal inputs, and available for either direct (stem
down to close) or reverse acting (stem up to
close) stroke direction. Actuators shall have a
field selectable stroke position on signal failure.
Models with spring return and non-spring return
shall be available. Non-spring return actuators
shall have manual override capability without
removal of the actuator cover or actuator. Spring
return models shall have manual override capabil-
ity under the cover, for emergency override during
periods of no power.
Auxilliary switches, auxilliary feedback, and high
temperature kits for steam applications, shall be
optional factory accessories for direct coupled
valve actuators.
Direct coupled valve actuators shall be manufac-
tured by the same company as manufactures the
valves. Actuators shall be UL and CSA listed,
manufactured under ISO 9001 International
Quality Control Standards.
