SAFETY SHUT-OFF VALVE TYPE 022
The type series safety shut-off valves 022, pressure rate PN 16 or ANSI 150, are to use for commercial and industrial gas-
installation . The shut-off valve 022 is designed in module construction .
In case of non acceptable values of outlet pressure (increased or decreased1), they automatically interrupt the gas flow .
The shut-off valves 022 are approved by German DVGW (Standard EN 14382) and is conform with PED .
