Globe valves mounted on a controller with electric actuator with
safety function to protect heating systems against exceeding
certain temperature or pressure limits.
The control valves consist of either a single-seated, unbalanced
Type 3213 Globe Valve or a single-seated, balanced Type 3214
Globe Valve together with a Type 5725 Controller with Electric
Actuator with safety function.
The control valves can take on the task of a shut-off valve within
safety interlock circuits triggered by the signal of a temperature
or pressure limiting device or upon a power supply failure.
The control valves are typetested by the German technical
inspectorate TÜV according to DIN 32730 and have been
defined as shut-off and control devices.
