LNG (Liquefied Natural Gas) is a key driver of the global energy transition.Across every stage of an LNG system—from cryogenic liquid storage and low-temperature transferto vapor return and high-pressure natural gas distribution—valves must deliver exceptional reliability, sealing performance, and safety. In the LNG industry, every material selection and design choice is a safety decision. LNG facilities continuously face: ·         Cryogenic temperatures (liquid LNG at approx. –162°C) ·         Two-phase flow transitions between liquid and vapor ·         High-pressure natural gas distribution after vaporization ·         Rapid temperature and pressure cycling ·         Potential ignition risks ·         Corrosive, vibrating, and harsh marine/terminal environments Valves are not just flow-control components—they are the core of system safety and operational stability.   🔥 Three Major LNG System Challenges — Solved by Anson Flow   Pain Point 1: Material Stability & Sealing Reliability in Cryogenic Service (Liquid LNG Section) Liquid LNG operates between –162°C and –196°C.At these temperatures, standard industrial valves may experience material shrinkage, seal hardening, stem leakage, or packing failure.

In industrial fluid systems, globe valves play a critical role in control, regulation and shut-off applications. At Anson Flow, our globe valve portfolio is designed for high performance, durability and flexibility — whether in steam systems, chemical plants, power stations or process pipelines. Globe Valves Explained Globe valves use a linear motion disk (or plug) which moves perpendicular to the flow, allowing fine regulation of flow rate and pressure. Unlike full-open/close designs, they are ideal for throttling, flow adjustment, and applications where precise control is needed. Key Characteristics of Globe Valves: ·                     Excellent throttling capability – Enables gradual flow changes and accurate control. ·                     Suitable for many media – From clean water, steam, gas to corrosive chemicals and high-temperature fluids. ·                     Material and design versatility – Available in carbon steel, stainless, duplex, special alloys; variants for high temperature/pressure and critical services. Limitations to Consider: ·                     Higher pressure drop when partially open compared to ball or gate valves. ·                     More frequent maintenance may be needed in abrasive or high-cycle services. ·                     Not always the best solution for full-bore pipeline isolation where minimal pressure loss is required. Applications of Anson Flow Globe Valves ·                     Steam & Power Generation – Precise control of steam flow, bypass lines, heater stations. ·                     Chemical & Petrochemical Plants – Regulation of corrosive fluids, catalyst feeds, acid services. ·                     Water Treatment & Desalination – Dosing, process control, and fine adjustment of flows. ·                     Oil & Gas & Subsea Systems – Special-material globe valves for high-pressure, high-temperature or sour service. Comprehensive Globe Valve Portfolio Our globe valve family covers a wide range of environments and service demands: ·                     AF-GVE Globe Valve: ANSI 150-900, PN10/16/25/40, JIS 10K/20K, sizes ½"-12". ·                     AF-GVC Cryogenic Globe Valve: ANSI 150/300, JIS 10K/20K, sizes ½"-6", engineered for ultra-low temperatures. With this breadth, Anson Flow supports everything from standard industrial service to the most extreme environments. Why Choose Anson Flow Globe Valves?

In industrial systems, every valve is more than just a part — it’s a safeguard for safety, reliability, and performance.Whether in oil & gas, water treatment, or power generation, traceability and certification are key to preventing costly downtime.One of the most essential documents proving this quality assurance is the EN 10204 3.1 certificate.   🔍 What Is EN 10204 3.1? EN 10204 defines the type of inspection documents supplied with metal products.A 3.1 certificate (also known as a Mill Test Certificate) confirms that the material supplied meets the required chemical and mechanical properties, verified by the manufacturer’s independent quality control department. It includes: ·         Chemical composition ·         Mechanical test results (tensile, yield, hardness) ·         Heat number and batch traceability ·         Confirmation of compliance with standards In short, it is the passport of quality and material authenticity.   ⚙️ Why It Matters in Valve Procurement 1.    Material Authenticity & TraceabilityEnsures the valve body, cap, and stem are made from verified material grades, preventing mismatched or counterfeit materials. 2.    Compliance with Global StandardsEN 10204 3.1 certification is often required for PED, API, and DIN compliance — essential for project acceptance and third-party inspections. 3.    Confidence in QualityProvides end-users and EPC contractors with documented assurance that each valve component meets design and safety expectations.   🧰 Anson Flow’s Commitment to Quality At Anson Flow, we take quality and traceability seriously.All our valves comply with EN 10204 3.1, ISO 9001, and API / DIN / BS standards.Each valve undergoes strict material verification, dimensional checks, pressure testing, and traceability by heat number. This ensures every Anson Flow valve — from ball valves to cryogenic or lined series — meets the highest quality standards demanded by global clients.   ✅ Conclusion Requiring EN 10204 3.1 certification is not just about paperwork — it’s about accountability, safety, and long-term reliability.When you choose Anson Flow, you choose a partner who values quality from raw material to final inspection.   Contact Anson Flow today to learn more about our certified valves and inspection system.Let’s build safer, more reliable flow control together. 👉 Explore Our Products | Download E-Catalogue
