Hard-Seal Stainless Steel American Standard Rising Stem Gate Valve
The Hard-Seal Stainless Steel American Standard Rising Stem Gate Valve is engineered for high-temperature, high-pressure, and abrasive media. Featuring an all-304/316 stainless steel body, Stellite-coated wedge disc, and exposed rising stem compliant with ASME B16.34, it excels in oil, chemical, and power industries. Operating from -29℃ to 425℃ at PN40/ANSI 300 pressure, it supports full-bore flow and bidirectional sealing for DN50-DN600 pipelines.
- Extreme Condition Durability: Withstands cryogenic (-29℃) to high-temperature (425℃) media including steam and sandy crude.
- Leak-Free Safety: Metal hard seal eliminates internal leakage; API 600-compliant stem design prevents blowout.
- Seamless Integration: ASME B16.10 face-to-face dimensions ensure direct compatibility with ANSI pipelines.
- Lifecycle Economy: >=10-year maintenance-free service (non-abrasive media) lowers total ownership cost.
Stellite overlay (>=HRC45) on disc/seat resists abrasion and oxidation, offering 5x longer lifespan than soft-seat valves.
01
Exposed stem threads with optional 2Cr13 (nickel-plated), 304, or 316 stems prevent hidden corrosion.
02
Wedge disc achieves API 598 Class IV sealing via metal-to-metal contact and pressure-assisted closure.
03
Bronze nut with trapezoidal thread and grease groove reduces manual torque by 30%.
04
Bolted bonnet allows in-line packing (graphite+304 wire) replacement without valve removal.
