VALVES AND ACCESSORIES

Product catalog summary
Specifications:
The document outlines various high-performance valves and accessories, including needle regulating valves for high-pressure lines up to 4 inches in diameter. These valves are available in materials such as Carbon Steel, Stainless Steel 316/316L, Brass, Duplex, Superduplex, Hastelloy, and Monel. They are categorized into Series 3000 (up to 255 bar), Series 6000 (up to 425 bar), and Series 10000 (up to 700 bar) based on pressure ratings.
Features:
Valves feature a special stem with a back seating function for packing changes during operation. The shut-off mechanism is metal-to-metal, with an optional soft seat. All valves are tested hydraulically and with helium per API 598 standards and come with EN 10204 3.1 certificates.
Materials and Components:
Components include the valve body, stem/obturator, bonnet, and packing gland, made from materials like F316/316L, Aluminium, Brass, and Special Alloys. Packing materials include Grafoil and PTFE.
Valve Series and Ratings:
Detailed specifications for different valve series include temperature and pressure ratings for materials like Carbon Steel, Stainless Steel, and Brass, along with Kv values and dimensions for various sizes and configurations.
High Temperature and Cryogenic Valves:
High-temperature needle valves are made from SS316/316L or F321, suitable for temperatures up to 800°C. Cryogenic valves are made from SS316/316L, with a temperature range from -268.9°C to 230°C, conforming to BS 6364 and BS EN1626 standards.
Connection Types:
Available connection types include NPT, BSP, SW, BW, and flanged connections, with specific dimensions and configurations for each type.
Testing and Certification:
All valves undergo rigorous testing, including helium and hydraulic tests, and are certified according to international standards, ensuring reliability and safety in high-pressure applications.
Material Specifications:
The document compares stainless steel grades, noting that SS 321 includes titanium to prevent carbide precipitation during welding, allowing operation at 800 ºC. F316/316L is suitable up to 450ºC at 100 bar, while F321 can be used up to 550 ºC at 100 bar and 650ºC at 50 bar.
Valve Options and Features:
Valves can be customized with anti-tamper devices, flanged connections, and are suitable for high temperature and cryogenic services. They can also be degreased and cleaned for oxygen service according to ASTM G93 standards.
Product Variants:
Various materials and configurations for valves and accessories are listed, including stainless steel, carbon steel, and brass. Options for handwheels include aluminium and bakelite, with additional features like PVC anti-tamper devices and level indicators.
