Norgren 8218200.0000.00000 Valve & Flow Control - G1/2
Part Number: 8218200.0000.00000
Quick Summary
Norgren 8218200.0000.00000 valve delivers reliable 2/2 NC control for gases and liquids in automated process lines. Engineers often struggle with maintaining leak-tight performance when handling contaminated fluids or rapid cycling, which can lead to unplanned downtime and increased maintenance costs. Certification specifics such as CE, SIL, or IP ratings are not listed in the provided data; verify details in the datasheet or with the supplier. Designed with a brass body and PTFE seat, it provides durability and chemical compatibility, while a G1/2 port supports straightforward installation. The operating range of -10 to 180 °C and 0 to 16 bar enables flexible deployment across multiple processes, delivering consistent performance and reducing total cost of ownership in high-cycle systems.

Feature: Brass body with PTFE seat provides robust chemical compatibility and long service life in demanding fluid applications. Business Impact: Reduces corrosion-related downtime and maintenance costs, improving only-minimal-interruption operation in chemical processing lines. Application: Ideal for inline brass angle seat valves handling gases and liquids in automated plants. Feature: Damped closing and back-pressure tight design minimizes surge, wear, and backflow risk. Business Impact: Protects downstream equipment, extends valve life, and stabilizes process pressures for more predictable batch control. Application: Critical in high-cycle dosing or sampling loops where pressure transients are common. Feature: Wide operating temperature and pressure range (-10 to 180 °C, 0 to 16 bar). Business Impact: Enables deployment across multiple media and environments without bespoke components, reducing part diversity and stocking costs. Application: Suitable for systems with aggressive fluids or temperature cycling. Feature: G1/2 port size and 2/2 normally closed function. Business Impact: Delivers straightforward integration with standard manifolds and compact control logic, lowering installation time and misconnection risk. Application: Fits common DIN/fieldbus manifold configurations in European facilities. Feature: Brass body with PTFE seat and corrosion-resistant construction supports contaminated-fluid service. Business Impact: Maintains seal integrity under challenging media, reducing leakage potential and warranty claims. Application: Suitable for harsher industries where media cleanliness varies. Feature: Pilot signal compatibility with liquid pilot options. Business Impact: Enables compact, low-energy pilots and simpler control loops, cutting overall actuation energy consumption. Application: Beneficial in compact control panels and retrofit projects where space is limited. This combination of material choice, mechanical damping, and versatile specifications provides a reliable, efficient solution for modern process automation, with an emphasis on installation simplicity and lifecycle cost reduction.

FAQs
The valve uses a standard G1/2 port and is designed for straightforward installation into existing DIN-compatible manifolds. Ensure a clean, dry thread sealant is used and verify alignment to avoid cross-threading. The 80 mm length and 65 mm height fit compact spaces, reducing cabinet depth requirements and enabling easier retrofits.
A 2/2 normally closed (NC) configuration provides a simple, fail-safe method to shut off flow when the actuator is de-energized. This is ideal for isolation in piping loops, ensuring immediate stop of media flow in an overpressure scenario, while allowing quick restart once control signals resume.
Yes. The brass body with PTFE seat is designed for chemical compatibility and resilience, while the operating range of -10 to 180 °C supports media with wide thermal profiles. Always confirm media compatibility from the datasheet for your exact fluid composition.
Certification specifics such as CE, SIL, or IP ratings are not listed in the provided data. To confirm regulatory compliance, consult the official datasheet linked in the product downloads or contact the supplier to obtain the latest CE, IP, or SIL documentation.
Damped closing minimizes pressure spikes and mechanical shock at switch-off, reducing wear on seals and downstream equipment. This translates to longer component life, lower maintenance frequency, and greater uptime in high-cycle systems such as automated dosing and process-control loops.
