211BT Bronze Globe Valve with PTFE Seat
Engineered for precision flow control in aggressive environments, the 211BT Bronze Globe Valve combines a virgin PTFE seat with rugged bronze construction to deliver leak-tight performance in water, oil, gas, and low-pressure steam applications. Designed to MSS-SP-80 standards, this valve excels in systems requiring chemical resistance, low maintenance, and reliable throttling.
Key Features & Benefits
✔️ PTFE Seat & DZR Trim – Virgin PTFE seat ensures chemical inertness and bubble-tight sealing, paired with dezincification-resistant brass for longevity in corrosive media.
✔️ Swivel-Type Disc Design – Reduces wear and ensures consistent sealing under high-cycle operation.
✔️ 125# WSP / 200# WOG Ratings – Certified for steam (125 PSI) and water/oil/gas (200 PSI) service.
✔️ Inserted Bonnet – Enhances pressure integrity and simplifies maintenance.
✔️ ASME B1.20.1-NPT Threads – Leak-resistant FNPT connections for quick, secure installations.

Why Choose the 211BT Over the 211B?
- Chemical Resistance: PTFE seat outperforms metal in corrosive or high-purity applications.
- Low Friction: Smoother operation with reduced torque requirements.
- Zero Contamination: Ideal for food-grade or pharmaceutical systems.
Ideal Applications
- Chemical processing lines
- HVAC hydronic systems with glycol solutions
- Industrial steam condensate return
- Oil/gas pipelines with acidic media
- Water treatment plants
