208B Bronze Gate Valve
The 208B Bronze Gate Valve combines MSS-SP-80 compliance and a rising stem design for precise flow regulation in commercial, industrial, and municipal systems. Engineered with a solid bronze disc and dezincification-resistant (DZR) trim, this valve ensures leak-free performance in water, oil, gas, and steam applications up to 200 PSI.
Key Features & Benefits
✔ Rising Stem Visibility – Clear visual indication of valve position for precise control
✔ Heavy-Duty Bronze Build – ASTM B62 body/wedge resists corrosion and wear
✔ 125# WSP / 200# WOG Rating – Certified for steam (125 PSI) and water/oil/gas (200 PSI)
✔ DZR Corrosion Defense – Trim components resist dezincification in aggressive media
✔ ASME B1.20.1-NPT Threads – Leak-proof FNPT connections for easy installation
