Feature: Brass body construction provides robust mechanical strength, corrosion resistance, and durability in tough industrial environments. Impact: This reduces lifecycle costs by minimizing replacement due to media exposure and wear, delivering higher uptime and predictable performance. Application: Ideal for inline control in process lines handling gases and liquids where cleanliness and material compatibility are critical. Feature: PTFE seat seal offers excellent chemical resistance and low leakage across a wide media range. Impact: It helps maintain tight shut-off and reduces maintenance frequency caused by seat wear or contamination. Application: Suitable for applications demanding reliable seals in contaminated fluids and mixed-media lines. Feature: 2/2 valve operation with NC (normally closed) logic provides straightforward control logic and predictable fail-safety. Impact: Simplifies electrical and pneumatic actuation, reducing wiring complexity and integration risk. Application: Fits standard automation schemes in compressed-air and fluid handling systems with G3/4 port connections. Feature: Damped closing minimizes surge pressure and backflow when the valve closes. Impact: Protects downstream equipment and reduces system instability. Application: Particularly valuable in systems with pulsating flow or sensitive instrumentation. Feature: Operating range from -10 to 180 °C and 0 to 10 bar covers broad process conditions. Impact: Enables multi-media service and reduces the need for part replacements when media or temperature vary. Application: Suitable for both gases and liquids in general-purpose control loops. Feature: Compact G3/4 format with standardized 82180 range and compatibility with Norgren/IMI Buschjost families. Impact: Streamlines spares, stocking, and maintenance planning while easing mounting and replacement in existing installations. Application: Ideal for retrofit projects and new builds in automation lines. Feature: Brass body and PTFE seat seal combine to deliver reliable performance in contaminated or dirty media. Impact: Improves service life, reduces unplanned downtime, and supports compliance with process-control standards. Application: Best suited for valve assemblies in industrial air, water, and chemical transfer lines.

FAQs
Install the valve by threading the G3/4 ports into the line, verifying correct orientation to avoid dead zones. The valve uses a 2/2 NC configuration, so it closes when unpowered; ensure the electrical/pneumatic control wiring is correct for fail-safe operation. Secure mounting to minimize vibration and ensure pilot signals are compatible with your system.
The valve supports media from gases to liquids across a broad range: -10 to 180 °C and 0 to 10 bar. The damped closing plus back-pressure tight design helps maintain stability during pressure fluctuations. The standard G3/4 port size accommodates common line installations and a 2/2 NC configuration provides predictable control in automation sequences.
Yes. The extended description notes suitability for contaminated fluids, aided by a PTFE seat and damped closing to minimize wear and leakage. For best results, use upstream filtration to limit abrasive particulates and ensure a clean control signal to protect seat integrity over time.
Certification details are not listed in the provided data. Check the attached datasheet for CE marking status and any SIL-ready variants. If regulatory compliance is essential for your project, contact Norgren technical support or consult the datasheet to confirm approvals for your region and media.
The ROI is driven by reduced leakage, longer service life from PTFE seating, and damped closure that lowers surge-related wear. The 2/2 NC configuration simplifies wiring and control logic, reducing installation costs. In practice, expect lower downtime and steadier process control across mixed-media lines.
