Bronze Globe Valve | 211B / 211BT Series | FNPT × FNPT Threaded Ends | 125 PSI WSP / 200 PSI WOG
RWV 211B / 211BT Series Bronze Globe Valves deliver reliable flow regulation for hydronic, potable water, and general plumbing systems. Designed for smooth throttling and long service life, these valves feature a swivel-type disc, inserted bonnet, and FNPT × FNPT threaded ends built to ASME B1.20.1 standards.
Choose between two precision-engineered seat configurations:
- 211B — Metal Seat: For rugged duty and consistent metal-to-metal sealing.
- 211BT — PTFE Seat: For superior chemical resistance and smooth shut-off under thermal stress.
Key Features & Benefits
- Precision Flow Control — Swivel-type disc ensures smooth throttling with minimal wear during frequent adjustments.
- Dual Seat Options — Metal (211B) or virgin PTFE (211BT) seat configurations to match system demands and media type.
- Durable Bronze Construction — ASTM B62 C83600 body and bonnet with DZR brass trim for dezincification resistance.
- Threaded FNPT × FNPT Ends — Comply with ASME B1.20.1 threads for quick installation and tight sealing connections.
- High Pressure & Temperature Rating — 200 PSI from 15 °F to 160 °F and 125 PSI max at 366 °F.
- MSS-SP-80 Compliant — Manufactured to industry standards for mechanical performance and service longevity.
