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 cast iron plug valves. It also specifies anti-static requirements, and the option of a steel or cast iron plug. This standard is applicable to short, regular or venturi pattern valves. The range of valves covered by this standard are given in table 1. Pressure/temperature ratings of the linings of lined valves are outside the scope of this scope.
