Norgren 8218301.0000.00000 Brass Angle Seat Valve - G3/4
Part Number: 8218301.0000.00000
Quick Summary
Norgren 8218301.0000.00000 brass angle seat valve provides reliable 2/2 control for gases and liquids. Engineers often struggle with leaks, seal wear from contaminated fluids, and unstable closures in high-flow lines. CE and SIL certifications, where applicable, plus robust IP ratings, support safe, compliant operation in European and hazardous environments. In practice, this valve's 20 mm nominal diameter, G3/4 port, PTFE seat, and damped closing translate to reliable automation performance and reduced maintenance. This combination supports efficiency gains, predictable cycle times, and easier integration into existing pneumatics platforms. For teams pursuing reduced downtime, this valve offers repeatable performance in harsh environments.

FAQs
Ensure proper port orientation and thread engagement for the G3/4 connection, and use correct torque per the valve datasheet to avoid leaks. Verify that the pilot signal lines are compatible with the chosen fluid and that the upstream and downstream plumbing accommodates 20 mm nominal diameter. Mounting should minimize vibration to preserve damped closing performance.
With a 2/2 NO configuration, the valve remains open when de-energized, providing a fail-safe path that can be closed on signal. This simplifies control logic for on-demand flow and reduces energy use because the valve only consumes power during actuation. In automation panels, pair with a compatible pilot valve to achieve rapid, repeatable cycling.
Yes. The brass body with a PTFE seat seal offers chemical compatibility and resistance to contaminants, reducing the likelihood of sticking and leakage. The damped closing minimizes wear on the seat during final closure, extending service life in dirty or viscous fluids and helping maintain consistent performance over time.
Industrial users should verify CE compliance and any applicable SIL or IP ratings for their specific variant and application. Always consult the supplier’s documentation for the exact version to ensure alignment with plant safety standards, regulatory requirements, and hazard classifications in your region.
The valve delivers lower downtime thanks to high flow with damped closing, reducing wear and energy losses. PTFE seating extends service life in contaminated lines, while simplified external-pilot control lowers wiring and maintenance costs. Over time, improved reliability and compatibility within the IMI Buschjost family can streamline procurement and spare-part management.
