A critical safety feature requiring stems to be blowout-proof. The stem cannot dislodge under pressure if the packing nut or gland loosens.

However, I can provide you with a of what MSS SP-99 covers, which will help you understand the document before you purchase or read it.

A process engineer must choose a fitting for 800°F steam service. By checking the pressure-temperature table in the PDF, they confirm that a standard 316 stainless fitting is insufficient and upgrade to a chromium-molybdenum alloy.

Cost-effective for non-corrosive, high-pressure environments. A critical safety feature requiring stems to be

This stage qualifies the design. It includes:

What is the of your application?

In the complex world of industrial piping and process control, standards are the backbone of safety and interoperability. If you are an engineer, a procurement specialist, or a manufacturer involved in instrumentation, you have likely encountered the standard. Emma felt a shiver run down her spine as she closed the PDF

Clarifies which products are covered and which are excluded (e.g., standard ASME B16.34 valves are typically excluded).

Multi-valve assemblies (2-way, 3-way, and 5-way) used to isolate, bleed, and calibrate instruments.

Understanding instrument valves is just one piece of the puzzle. If you work in process piping, you may also benefit from related standards such as (Power Piping) or ASME B31.3 (Process Piping), which heavily rely on MSS standards to dictate how instrument valves should be installed in the field.
