3/4" NPT Full Port Brass Ball Valve – 600 PSI CWP (FBB-75)
The PneumaticPlus FBB-75 is a professional-grade 3/4" NPT Full Port Brass Ball Valve rated for 600 PSI CWP / 150 PSI WSP. Constructed with a forged brass body (C37700) and blow-out proof stem for manual shutoff applications within the published ratings, this model features a 0.75" full port bore (A). This provides a larger internal opening to help reduce flow restriction.
- Bore (Full Port) design with a 0.75" internal opening (A) provides a larger internal opening to help reduce flow restriction.
- Vacuum Service rated up to 29" Hg, making it suitable for pressurized service and vacuum applications up to 29" Hg.
- Forged brass body (C37700) provides durability for industrial environments.
- PTFE seats and packing provide a reliable seal and operation across a wide temperature range of -20°F to 365°F.
- Blowout-proof stem ensures safer operation under pressure.
- Lever handle for manual on/off control.
- 600 PSI CWP / 150 PSI WSP rating (per manufacturer specifications).
Common Applications & Use Cases
The FBB-75 is suitable for various industrial and commercial environments based on its flow ratings and construction:
- Main Air Header Isolation: Suitable for manual isolation on larger diameter lines where 3/4" FNPT connections are used.
- High-Flow Manifolds: Full port bore (0.75") and Cv 29.76 can be used as reference points when selecting a valve for higher-flow shutoff needs.
- Industrial Machinery Supply: Suitable for equipment or systems that use 3/4" FNPT shutoff valves and operate within the published pressure, temperature, and media compatibility requirements.
- Facility Maintenance: Supports manual isolation for service and maintenance within the published ratings.
