* The 4 column selection valve, CST4UW, is an 8 position valve and needs a 4 x 2 actuator.
** The 6 column selection valve, CST6UW, is a 12 position valve and needs a 6 x 2 actuator.
Two position
standard electric
actuators may be operated manually
by a toggle switch or automatically
by any data system with momentary
contact closures or 5 VDC negative
true logic outputs. A complete system,
the actuator includes interface cable,
power cord, and manual controller
assembly with position indication.
Multiposition
(selector) models work
with any of our multiposition valves.
The manual controller with LED display
allows the user to step sequentially
from one position to the next or to
return to Position 1 (Home). A data
system with momentary contact
closures can direct the step and
home functions; 5 VDC negative true
logic outputs provide direct position
access. A 20-conductor interface
Valco
Cheminert
cable permits the system to step
the actuator sequentially, move the
actuator directly to any position, and
read the actual valve position.
Standard electric actuators can be
ordered with closemount hardware, a
standoff, or just the standoff mounting
hardware, if your valve already has
a standoff. Valves which will be
mounted in ovens require a standoff
assembly so that the actuator is
located out of the heated zone.
The actuator’s rotation (two position)
or number of positions (multiposition)
must be properly matched to the
valve’s. If you are converting a manual
valve to electric actuation and have
any doubts about which actuator and
hardware you need, call our sales or
technical staff for assistance.
