Norgren 8218701 Brass Angle Seat Valve - 2/2 - G2 Port
Part Number: 8218701.0000.00000
Quick Summary
Norgren 8218701.0000.00000 Brass Angle Seat Valve enables high-flow control for gas and liquid lines in process automation. Operators often face contaminated process fluids, back-pressure challenges, and slow valve closure that throttle cycle times. Certification considerations include CE compliance and the availability of IP-rated and SIL-ready variants; verify exact certificates in the datasheet. Built with a brass body and PTFE seat, this valve delivers durable, reliable performance across demanding industrial environments, supporting easy installation, longer service life, and scalable automation across a range of fluids and applications. The combination of robust materials with flexible control signals makes it a dependable choice for critical flow control in plant-wide systems.

Feature → Business Impact → Application: Brass body with PTFE seat provides corrosion resistance and chemical compatibility, reducing maintenance costs and extending valve life in dirty or aggressive process streams; ideal for chemical processing, water treatment, and food/pharma lines. High flow rate with damped closing and back‑pressure tight performance translates to faster cycle times and reduced leak potential, improving overall process efficiency and vacuum handling in packaging and automation lines. External pilot signal compatibility enables flexible control architectures, allowing remote or fluid-powered pilots to be used in multi-zone systems, lowering wiring complexity and enabling easier retrofit in existing plants. Operating from -10 to 180°C and 0 to 3 bar expands usable applications across petrochemical, beer/wine, and beverage processing where temp and pressure conditions vary. 50 mm nominal diameter and G2 port size ensure compatibility with standard piping and easy installation in new or retrofit projects. The 2/2 NO configuration offers straightforward integration into current pneumatic control loops, reducing integration risk and accelerating commissioning. Contaminated fluids are accommodated thanks to the seat seal material (PTFE) and the damped closing design, delivering reliable shut-off in challenging environments.

FAQs
Yes. The valve uses G2 port size with a 50 mm nominal diameter, which aligns with standard pneumatic and plumbing fittings, simplifying installation and retrofit projects in existing pipelines.
The valve operates from -10 to 180°C and handles 0 to 3 bar (0 to 44 psi), making it suitable for broad process conditions and many industrial fluids.
Best for high-flow control of gases and liquids in contaminated fluid environments, including process automation, vacuum handling up to 90%, and installations requiring 2/2 valve operation with robust durability.
Yes. The design includes damped closing and back-pressure tight sealing to minimize surge, reduce leakage, and improve reliability in fluctuating process pressures.
External pilot signaling can be fluid-based, offering flexible control options in multi-zone or retrofit systems, enabling remote actuation without extensive electrical wiring.
