Norgren 8218200.9101.23050 Brass Angle Seat Valve - IP65
Part Number: 8218200.9101.23050
Quick Summary
Norgren 8218200.9101.23050 brass angle seat valve provides high-flow control for gases and liquids in process automation. Engineers often struggle with contaminated fluids, slow closures, and back-pressure leaks that disrupt cycle stability and uptime. With IP65 ingress protection, a brass body, and PTFE seat, this valve offers rugged reliability across harsh environments and broad temperature and pressure ranges. Its 2/2 NC configuration and G1/2 port size simplify integration into existing manifolds, while external pilot signals expand control options for compact plant layouts. Designed for efficiency and compliance, it supports vacuum applications up to 90% and operates from -10 to 180 °C and 0 to 16 bar, delivering measurable value for OEMs and maintenance teams.

FAQs
When retrofitting, verify port compatibility with G1/2 connections and confirm the 15 mm nominal diameter aligns with existing manifolds. Use a two-way, two-position NC arrangement (2/2) and ensure proper orientation for flow direction. The option for a fluid external pilot allows remote actuation without electrical wiring, which simplifies space-constrained installations and enhances safety in certain environments.
Yes, the valve is rated for vacuum up to 90% in appropriate configurations. Users should ensure the upstream and downstream connections maintain the specified 0 to 16 bar operating range when not under vacuum, and account for potential sealing performance under high differential pressures. The damped closing and PTFE seat help minimize leakage and surge effects in vacuum lines.
External pilot control can be fluid-based, enabling actuation without electrical input. This is beneficial for plant areas with explosion-protection requirements or where electrical noise is a concern. Fluid pilots offer reliable remote operation, particularly in inline manifolds or compact automation cells where wiring is impractical or undesired.
The NC (normally closed) configuration ensures the valve remains shut in de-energized conditions, providing a fail-safe default for pressurized gas lines. When the external pilot activates, the valve opens to allow flow. The combination of a brass body and PTFE seat delivers reliable seating and back-pressure tightness, reducing unintended releases and improving process stability.
Key factors include using the PTFE seat seal to resist chemical attack and wear, maintaining clean fluids to prevent seat clogging, and ensuring IP65-rated protection is preserved through proper enclosure selection. Regular inspection of the brass body for corrosion, verification of port integrity, and checking external pilot plumbing for leaks will help sustain performance over time.
