Norgren 8472300.0000.00000 Brass Angle Seat Valve - G3/4
Part Number: 8472300.0000.00000
Quick Summary
Norgren 8472300.0000.00000 Brass Angle Seat Valve is designed for reliable gas and liquid control in compact manifolds. Engineers often struggle with flow integrity when using fluids with particulates or under vacuum conditions, risking leaks and downtime. Typical certifications for this family include CE marking for European compliance, IP-rated enclosures for harsh environments, and SIL-capable variants in safety-critical lines, providing confidence across projects. This valve delivers fast, damped shut-off and a visual position indicator, reducing misalignment during assembly. By selecting this model, you gain robust brass construction, PTFE seat seals, and a compact G3/4 port footprint, which translates into lower installation costs and easier maintenance while ensuring consistent performance in demanding applications.

FAQs
The 8472300 model uses a standard G3/4 port size, enabling straightforward integration with common pneumatic and fluidic manifolds. It supports typical mounting patterns found in automation frames, panels, and compact manifolds. For best results, pair with compatible 3/4 inch fittings and ensure seal integrity via PTFE seat seals. If you’re retrofitting, verify bore alignment and gasket compatibility to prevent leaks and ensure proper visual position indicator operation during assembly.
Damped closing reduces rapid valve actuation and minimizes pressure spikes, yielding smoother shut-off in both gas and liquid lines. In 2/2 NC operation, this translates to lower system shock, reduced wear on downstream components, and quieter operation—beneficial in compact automation cells where noise and vibration affect tooling alignment and cycle times.
Yes. The valve is designed for contaminated fluids and is vacuum-tolerant up to 90%, making it suitable for challenging process environments. The brass body and PTFE seat seals provide good chemical compatibility and mechanical resilience, which helps maintain sealing performance and reduces maintenance in dirty or partially evacuated systems.
This valve family commonly features CE marking for European compliance and has variants with IP-rated enclosures and SIL-capable configurations for safety-critical applications. While exact certifications vary by model, selecting the 8472300 series typically aligns with industrial standards for safety, reliability, and environmental protection relevant to gases and liquids in automation settings.
Adopt routine inspection of the visual position indicator and seal condition, verify PTFE seat integrity, and keep the port clean from particulates that could cause sticking. Schedule periodic valve cycling to prevent seat galling and check for leaks at the brass body joints. The combination of durable brass, PTFE seals, and a damped closing mechanism supports higher MTBF, reduces unplanned downtime, and lowers total cost of ownership over time.
