Technical Information
Application:
Heating and cooling systems.
The thermostatic heads 6402-00/6402-09/6412/6602/6662 can be used in conjunction with a heat conducting base as a contact sensor or with an immersion sleeve as an immersion sensor.
Thermostatic head 6672 as an immersion sensor without immersion sleeve. Sealed to the capillary tube via clamping joints.
Functions:
Medium temperature control with thermostatic valve bodies and three-way valves.
Temperature range is limited on both ends and can be blocked using covered stop clips.
Control behavior:
Proportional controller without auxilliary energy. Liquid-filled thermostat. High pressure power, lowest hysteresis, optimal closing time.
Nominal temperature range:
The setting range is
10° C to 40° C,
20° C to 50° C,
20° C to 70° C,
40° C to 70° C or
60° C to 90° C.
Temperature:
Maximum sensor temperature
50° C with thermostatic head 6412,
60° C with thermostatic head 6402,
80° C with thermostatic head 6602,
90° C with thermostatic head 6672 and
100° C with thermostatic head 6662.
