Norgren 8450200.0000.00000 Brass Angle Seat Valve - G1/2
Part Number: 8450200.0000.00000
Quick Summary
Norgren 8450200.0000.00000 brass angle seat valve provides reliable on/off control for gas and liquid lines. Engineers often struggle with leaks, contamination, and unpredictable closure that cause downtime; this valve offers a visual position indicator and dampened closing to mitigate those risks. While the data sheet does not explicitly list CE, SIL or IP ratings, verify CE marking, SIL compatibility and IP protection class for your installation. Designed for compact pneumatic systems, it supports G1/2 port size and 2/2 NC operation, enabling versatile installation in automation lines. This combination delivers reliable performance, easy integration with existing manifolds, and reduced maintenance in demanding manufacturing environments.

FAQs
Yes. The valve uses a standard G1/2 port thread and 2/2 NC configuration, allowing straightforward replacement in compatible manifolds. For optimum performance, verify port alignment, tightening torques, and seating with PTFE seal, ensuring no cross-threading during installation.
The valve supports operating pressure from 0 to 16 bar and temperatures from -10 to 60 °C. This makes it suitable for a broad range of pneumatic and hydraulic media, with adequate headroom for typical industrial processes.
Yes. The assembly is designed for contaminated fluids and can tolerate vacuum up to 90%, expanding its use in filtration, recycling, and handling lines where cleanliness is not guaranteed and pressure differentials are common.
The data provided does not specify CE, SIL, or IP certifications. Verify with the supplier or request the current datasheet and certification attestations before compliance audits, ensuring the exact variant meets your regulatory and safety requirements.
Dampened closing reduces hydraulic and pneumatic shocks during shut-off, which minimizes wear on upstream and downstream components, lowers maintenance intervals, and improves overall system reliability. This translates to lower lifecycle costs and less downtime in high-cycle applications.
