This manual provides technical specifications, material options, pressure‑temperature ratings, ordering information, and accessories for Swagelok pin‑type…
The Swagelok pin‑type union valves A‑317 A, N series and HN series are designed for harsh working environments. They offer pressure ratings up to 10 000 psig (689 bar) and temperature ranges from –53 °C to 232 °C with PTFE filler, or up to 648 °C with Grafoil filler. Valve bodies are available in 316 stainless steel and alloys 400, 20, 600, C‑276, as well as titanium, with flow coefficients (Cv) ranging from 0.35 to 2.4.
The document includes detailed ordering instructions, material code substitutions, optional accessories, cleaning and packaging procedures, and execution‑mechanism options such as pneumatic actuators. Safety and quality‑guarantee information are also provided for proper selection and use in various industries. This manual is written in Chinese.
