Gas shut-off valves with electromagnetic actuator unified KZGEM-U, are designed for use as a shut-off device of pipeline trunk lines with working medium - natural gas according to GOST 5542, vapour phase of reduced hydrocarbon gas according to GOST R 52087 or air.
Valves are produced in several versions differing from each other by nominal diameter, nominal pressure, type of connection to the pipeline, method of body execution.
Operating conditions:
- ambient temperature at operation from plus 10C to plus 400C;
- relative air humidity not more than 80 % at temperature 250C;
- atmospheric pressure from 86 kPa to 106, 7 kPa.
