A gas shutoff valve complying with what standard is permitted on 5 psig pressure gas lines?

• A. ASME B16.22
• B. ASME B16.33
• C. ASTM F876
• D. ANSI Z21.58

Answer: (B)

A gas shutoff valve on 5 psig pressure gas lines must comply with ASME B16.33 standards because this specific standard governs the design, materials, and testing of gas valves for use in gas pipe applications. ASME B16.33 is particularly focused on metallic valves and outlines essential performance requirements for valves that directly relate to their functionality on gas lines operating at specific pressures. This standard ensures that the shutoff valves are safe and effective for use in various applications, including those involving natural gas or other types of gas. It encompasses criteria that address the structural integrity and reliable operation of the valves under the conditions they will encounter, thus providing necessary assurance of performance at 5 psig. In contrast, the other standards listed cover different aspects: ASME B16.22 pertains to copper and copper alloy fittings, ASTM F876 deals with cross-linked polyethylene (PEX) pressure pipes and fittings, and ANSI Z21.58 relates to gas-fired space heating equipment but does not specifically address shutoff valves on gas lines.
