Cheminert's new
Model C52
(HPLC)
and
Model C62
(low pressure)
injectors are integrated motor/valve
assemblies designed specifically to
be built into an OEM system. Using
the well-proven Cheminert injector
designs and the 24 volt motor from
our popular microelectric actuators,
the C52 and C62 need only to be
connected to the instrument's power
supply.
Control is simplified to require a single
contact closure; the injector’s position
is determined by whether the closure
is held high or low. There's even an
easy way for the instrument to confirm
the valve’s position by sensing the
output from a built-in sensor.
In the default control mode, a contact
closure moves the injector from load
to inject, where it remains until the
contact is broken and the injector
reverts to the load position. A simple
jumper change shifts the mode to dual
contact closure, in which one contact
closure shifts the injector to inject
and a second is required to shift it
back to load. Jumper settings can also
be modified to change the motor’s
degree of rotation so it can be used
with any of the valve models available.
All these features are built into a
compact and lightweight package
and are available in 4, 6, 8, and 10 port
configurations.
Model C3
is a unique injector with
a syringe injection port centered on
the rear face of the valve (opposite
the handle or actuator), allowing
convenient syringe insertion when the
valve is mounted on an actuator inside
an instrument.
Model C2V
is designed specifically
for use in an autosampler. It is like the
standard C2 except that the sample
port is perpendicular to the valve axis.
This permits the valve and actuator
to be installed horizontally, while the
syringe loads the injector vertically.

universal actuator
The new universal actuator for OEMs oper-
ates virtually any Valco or Cheminert rotary
valve – two position and selector alike –
greatly simplifying the electronic aspect of
instrument design.
