Norgren 8450400.0000.00000 Angle Seat Valve - 2/2
Part Number: 8450400.0000.00000
Quick Summary
Angle Seat Valve 8450400.0000.00000 provides reliable NC or NO control for gases and liquids in industrial automation. In rugged plant environments, contamination, slow response, and seat wear drive maintenance costs and downtime. The valve features a brass body and PTFE seat seals with 2/2 operation, dampened closing, a built-in visual indicator, and optional reversed flow—all aimed at simpler diagnostics and safer operation. While the dataset notes German origin and a broad operating range (-10 to 60 °C, 0 to 10 bar) it does not specify CE, IP, or SIL certifications; verify your regulatory requirements during procurement. Designed for gas and liquid service in process automation, it helps engineers reduce spare parts, simplify installation, and improve system reliability.

Flexible control with NC/NO interchangeability and 2/2 operation enables quick process reconfiguration and reduces spare-parts inventory, especially in multi-product lines. In practice this means engineers can adapt automation sequences without hardware changes, saving commissioning time and minimizing downtime in batch or continuous processes. Dampened closing minimizes flow-induced shocks and pressure surges in delicate lines, improving system longevity and protecting instrumentation while the compact brass body supports straightforward installation in crowded panels. The built-in visual position indicator speeds maintenance checks and fault diagnosis during shifts, and PTFE seat seals offer reliable sealing across contaminated-fluid applications, extending service life in challenging environments. With operating range -10 to 60 °C and 0 to 10 bar, the valve suits a broad set of process conditions, while compatibility with standard G1 ports simplifies replacement and spares planning. This product line benefits from consistent sourcing through Norgren and IMI Buschjost, ensuring easy access to spares and replacements within established plant architectures.

FAQs
Yes. The valve is specified with a G1 port size and a brass body, making it compatible with standard G1 threaded fittings commonly used in industrial fluid and gas lines. For best results, use PTFE seat seals and verify torque recommendations from the installation manual to ensure leak-tight performance in your system.
Key specs include a G1 port size, brass body, PTFE seat seal, NC function, and 2/2 valve operation. Temperature range is -10 to 60 °C with an operating pressure range of 0 to 10 bar. It features a dampened closing action and a visual position indicator to simplify diagnostics and reduce commissioning time.
The extended description notes compatibility with contaminated flow fluids and a vacuum capability up to 90%. This makes it suitable for challenging process lines where particulates are present and vacuum-assisted applications, provided system design accounts for seal materials and lubrication needs in those conditions.
The provided data does not specify CE, IP, SIL, or other certifications. When selecting for regulated environments, confirm applicable certifications with the supplier and ensure the valve configuration (materials, seals, and actuation) meets your project’s regulatory requirements.
The brass body with PTFE seals offers robust wear resistance and reliable sealing, reducing leakage-related maintenance. NC/NO interchangeability and 2/2 operation simplify reconfiguration, lowering downtime during changeovers. The integrated visual indicator speeds inspection, contributing to shorter maintenance windows and improved uptime in automated processes.
