1/2" NPT Full Port Brass Ball Valve – 600 PSI CWP (FBB-50)
The PneumaticPlus FBB-50 is a professional-grade 1/2" NPT Full Port Brass Ball Valve engineered for reliable flow control in Water, Oil, and Gas (WOG) applications. Rated for 600 PSI CWP and featuring a blow-out proof stem, it serves as a high-durability isolation valve for air lines and fluid manifolds. This model features a 0.59" full port bore (A), designed to help maintain airflow and reduce pressure drop in pneumatic systems.
- Bore (Full Port) design with a 0.59" internal opening (A) helps minimize flow restriction at the point of use.
- Vacuum Service rated up to 29" Hg, making it suitable for both pressurized and vacuum-based systems.
- Forged brass body (C37700) provides enhanced durability in demanding shop and industrial environments.
- PTFE seats and packing provide a reliable seal and smooth operation across a wide temperature range.
- Blowout-proof stem ensures safer operation under pressure.
- Quarter-turn handle allows for fast shutoff with a clear visual of the open/closed position.
- 600 PSI CWP / 150 PSI WSP rating for air, water, oil, and compatible fluids.
Versatile Applications & Use Cases
The FBB-50 is designed for reliability across a wide spectrum of industrial, commercial, and residential environments:
- Shop Air Zone Isolation: Ideal for isolating compressor distribution lines and specific shop air zones.
- Shop Air Manifolds & Drops: Full port design helps maintain flow when feeding manifolds, hose reels, and multiple point-of-use connections.
- Machine Drops & Point-of-Use Isolation: Provides reliable manual isolation for pneumatic machinery and equipment at the drop point.
- Process Lines & General Purpose Fluid Control: Heavy-duty forged brass construction is suitable for commercial and industrial fluid shut-offs.
- Facility Maintenance: Allows for secure, reliable manual isolation of pneumatic machinery for repairs without facility-wide downtime.

Frequently Asked Questions
Q: Is the FBB-50 full port or standard port?
A: Full port design with a 0.59" bore (A) to help minimize flow restriction.
Q: Is this valve safe for use with compressed air?
A: Yes. The FBB series is specifically rated for 600 PSI CWP (Cold Working Pressure) and includes a blow-out proof stem for safer operation under pressure.
Q: Can I use this for drinking water?
A: No. This product contains chemicals, including lead, known to the State of California to cause cancer and reproductive harm. It is not intended for potable water use.
Q: What thread sealant should I use for installation?
A: For a reliable NPT connection, we recommend using high-quality PTFE tape or a dedicated pipe thread sealant suitable for brass fittings.
