Scope

This standard specifies the terms and definitions, technical requirements, test methods, inspection requirements, marking, packaging, transportation, and storage for low-temperature pilot safety valves (hereinafter referred to as safety valves).
This standard applies to pilot safety valves for low-temperature evaporated gas media with a nominal pressure of less than or equal to PN100, a nominal size of less than or equal to DN500, an operating temperature of not less than -196°C, and a minimum set pressure of 0.1 MPa.
Pilot safety valves for low-temperature evaporated gas media with a set pressure of 0.06 MPa to 0.1 MPa can be used as a reference.
