MSS SP-99 is the standard practice for Instrument Valves. Established by the Manufacturers Standardization Society (MSS), it governs the design, materials, and testing of small valves and manifolds commonly used in control and sampling piping systems. 📋 Scope and Overview
Application: Covers small valves and manifold valves designed for instrument, control, and sampling systems.
Sizes: Applies to nominal pipe sizes (NPS) 2 inches and smaller.
Pressure Ratings: Covers systems with pressure ratings of 15,000 psi (103.4 MPa) and lower at 100 °F (38 °C). mss sp99 pdf
Supported Valve Types: Includes needle valves, packless valves, ball valves, plug valves, check valves, and multi-valve manifolds. 🔑 Key Features of the Document
Material Specifications: Outlines the compliant chemical and mechanical properties required for the valve bodies and parts.
Burst Testing: Establishes rigorous hydrostatic burst pressure testing to verify the structural integrity of the valve shells.
Cold Working Pressure (CWP): Standardizes the calculations and limits for maximum allowable pressure at ambient temperatures.
Proprietary Tolerance: Because instrument valves often use manufacturer-exclusive sealing technologies, the standard focuses on safety and performance rather than limiting dimensions or restricting specific component designs. 🛒 Where to Access the PDF Often include guidance on installation, bolt torqueing, and

MSS SP-99 is a standard published by the Manufacturers Standardization Society (MSS) of the Valve and Fittings Industry. The "SP" stands for Standard Practice. Specifically, MSS SP-99 covers the requirements for Instrument Valves and Fittings used in process piping systems.
These components are typically found in:
Unlike standard industrial valves, instrument valves (such as needle valves, ball valves, and manifold valves) are designed for smaller bore applications, often for pressure gauges, transmitters, and other instrumentation.
