Heated Valve Enclosures

valve oven for Valco valves
Heated valve enclosures
close move

These insulated valve ovens 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 below 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.

Available in: 110 VAC
230 VAC

Non-CE; use restricted within the EU.

Heated valve enclosures - 110 VAC

Includes insulated enclosure and heater assembly (standard heater block, heater cartridge, line cord).
Insulation is 1/2" thick, so internal dimensions are 1" smaller than the exterior size given below.

TECH TIP

Heated valve enclosures provide a way to heat valves. A GC's auxiliary temperature zone controller or a separate independent instrumentation temperature controller is required to maintain the valves at a set temperature.
