SCOPE
1.1 This Standard Practice applies to small valves and manifold valves developed for and predominately
used in instrument, control, and sampling piping systems. It covers steel and alloy valves of nominal pipe
size (NPS) 2 and smaller, and pressure ratings of 15,000 psi (103.4MPa) and lower at 100 ° F (38° C). See MSS SP-99 for instrument valves
not involving code applications.
1.2 This Standard Practice applies to instrument valve designs including, but not limited to, needle
valves, packless valves, ball valves, plug valves, check valves, and manifold valves. Instrument valves
are generally of proprietary design. This Standard Practice is not intended to define or limit designs,
construction, performance, envelope dimensions, or valve types.
1.3 The application of valve type, size, rating, materials of construction, and suitability for the service
are the responsibility of the purchaser and are outside the scope of this Standard Practice.
