These insulated enclosures allow
valves to be operated at temperatures
independent of other controlled
zones of analytical instruments. The
compact construction and minimum
power dissipation enable mounting
within larger, lower temperature zones
without significantly raising the larger
oven’s minimum temperature or
impairing its programmability.
All enclosures include a heater block
and a heater cartridge with line
cord. The product number chart lists
the heater size typically required to
heat the valve(s) to the indicated
temperature. Holes are provided in the
heater block for Perkin Elmer, Agilent,
and Varian temperature sensors, with
an additional thermocouple hole
permitting temperature readout.

Since 1/32" W type valves are smaller,
they require a special heater block;
enclosures for 1/32” valves are denoted
by asterisk (*) in the price chart below.
Note:
Heated valve enclosures
provide a way to heat valves. A
GC’s auxiliary temperature zone
controller or a device such as our
ITC (instrumentation temperature
controller) is required to maintain
the valves at a set temperature.
Includes insulated enclosure and
heater assembly (standard heater
block, heater cartridge, line cord).
Standard voltage: 110 VAC. For a
230
VAC model, add -220 to the prod-
uct number. Insulation is 1/2" thick,
so internal dimensions are 1" smaller
than the exterior size given below.
