about standoffs
Keyed standoff assemblies are used with selector
(multiposition) microelectric actuators, to key the
valve body to the actuator and standoff so that the
actuators can self-align and operate valves with
any number of positions.
Valco selectors are not keyed unless ordered with
a microelectric actuator. To install a microelectric
actuator on an existing Valco selector, the key (pin)
must be removed from the actuator clamp ring
assembly. This can be done easily with a pair of
pliers.
See page 207, top and bottom illustrations, for
drawings of keyed standoff assemblies with
multiposition microelectric actuators.
Microelectric actuators
for selectors
Standard voltage 24 VDC. Includes autosensing 24 VDC power supply.
Standoff version includes a 2" standoff. 3", 4", and 6" standoffs are also available.
Consult the chart below to determine which actuator model is best suited for your valve.

RS-232 interface cable
I-22697
Multi-drop cables
for multiple microelectric actuators
Multi-drop cables permit a single serial port (RS-232) to control multiple
microelectric two position and selector actuators. Cables have one female DB9
and 2 to 8 male DB9 connectors – approximately 6" long.
Note:
The RS-232 interface cable (I-22697), above, is required for
each
actuator.
