But the more she uncovered, the more she realized that some secrets were meant to remain hidden. And that some mysteries were better left unsolved.

The standard is the definitive industry guideline for the design, manufacturing, and testing of instrument valves used in high-pressure and critical process piping systems . Developed by the Manufacturers Standardization Society (MSS) of the Valve and Fittings Industry, this standard ensures safety, reliability, and uniformity across diverse industrial applications.

An instrument valve is a functional classification rather than a single specific design. MSS SP-99 encompasses a wide array of valve configurations necessary to service different system setups. These include: Covers small valves and manifold valves designed for

, officially titled Instrument Valves , is a standard practice developed and maintained by the Manufacturers Standardization Society (MSS) of the Valve and Fittings Industry. An MSS Standard Practice serves as the industry’s benchmark—a "basis for common practice by the manufacturer, the user, and the general public". The standard applies to small valves and manifold valves developed for and predominantly used in instrument, control, and sampling piping systems, covering steel and alloy valves of nominal pipe size (NPS) 2 and smaller , with pressure ratings of 15,000 psi and lower at 100 °F . The standard is maintained under the consensus of MSS Technical Committee 115, Instrument Valves .

Proper stem packing compliance minimizes fugitive emissions of hazardous gases.

SP-99 is specifically for the small valves you see attached to pressure gauges, transmitters, and hydraulic panels.
