what are Gate Valves?

The 04-SAMSS-001 specification, in conjunction with the purchase order, lays down the minimum requirements for various types of gate valves used in industrial applications. These gate valves include steel, bolted bonnet, pressure seal bonnet, flanged, and butt-welding end gate valves of outside screw and yoke (OS&Y) construction.

The specification covers a broad range of nominal pipe sizes (NPS) from 1 through 24 for Classes 150 through 2500, as defined by API STD 600. Additionally, it extends the size range to include NPS 26 through 60 for Classes 150 through 600, thus encompassing a wide variety of valve sizes to meet different project requirements.

The gate valves specified in 04-SAMSS-001 are designed to handle wet sour liquid or gaseous hydrocarbon services with design temperatures ranging from -18 to 400°C. This makes the valves suitable for various applications within the oil and gas industry, where exposure to corrosive hydrocarbons is expected.

To address specific scenarios and applications, the specification includes additional requirements for special conditions in various appendices:

  • Appendix A: Requirements for Pressure Seal Gate Valves
    This appendix outlines the specific requirements for gate valves with a pressure seal bonnet design, which provides enhanced sealing capabilities for high-pressure applications.
  • Appendix B: Low Temperature Services from -45 to -18°C
    This appendix addresses the unique challenges posed by low-temperature applications and specifies the necessary design considerations and material requirements to ensure the valve’s proper functioning in extreme cold conditions.
  • Appendix C: Cryogenic Temperature Services from -45°C and below
    For cryogenic applications, where temperatures are below -45°C, this appendix sets forth stringent requirements for the gate valves to withstand extreme cold and prevent operational issues.
  • Appendix D: Steam Services
    This section covers gate valve requirements for steam services, including specific considerations for high-temperature and high-pressure applications.

In conclusion, the 04-SAMSS-001 specification serves as a comprehensive guideline for selecting and designing gate valves that can withstand demanding conditions encountered in the oil and gas industry. By complying with these requirements, operators and manufacturers can ensure the safe, reliable, and efficient operation of gate valves across various applications and environments.
