Gas sampling and gas conditioning technology 6-5.1.1-ME
8 APPLICATIONS
In analysis technique, often temperatures must be kept above the sample gas dew point. Therefore, it
is absolutely necessary to avoid cold spots. In order to ensure this, the temperature regulated M&C
three-way valves V3/2-
H… and MV3/2 H are used for the cut-off or switching-over of sample gases
and test gases up to an operating temperature of 180 °C.
9 DESCRIPTION
The M&C electrically heated valves are fixed on a mounting plate, decoupled from heat and covered
with an insulated enclosure. The heater consists of a heating element with high capacity. The tem-
perature is adjustable on the integrated thermostat up to 180 °C with high temperature limiter and low
temperature alarm. The heat insulated enclosure with a bushing for the dial thermometer is equipped
with quick acting bentlever closures. The connection box with integrated thermostat is installed outside
the enclosure on the mounting plate. Version V3/2-H/PE has got an additional connecting box for the
contact output of the position identification. The power supply for the solenoid valves version MV3/2-H
is 24V DC and the additional connecting box is installed on the mounting plate. In order to prevent
cold spots, the connecting fittings are heated by means of thermal conducting jaws. The electrically
heated sample lines type 3/4/5-N/M/H are fixed with mounting brackets.
