scope:

This European Standard specifies requirements for the valve seat and body pressure/temperature ratings and the design, including materials, dimensions, operation, performance, testing and marking of lubricated, soft seated and lined plug valves having a steel shell. It also specifies anti-static requirements, an optional fire tested design and the option of a steel or cast iron plug. This European Standard is applicable to short, regular or venturi pattern valves. The range of valves covered by this European Standard are given in Table 1. Pressure/temperature ratings of the linings of lined valves and flange attachment methods are outside the scope of this European Standard.
