Specification
ANSI 1500LBS Forged Steel Manual High-Pressure Self-Sealing Welded Gate Valve
I. Product Overview: Precision Interception for High-Pressure Applications
Newway’s ANSI 1500LBS forged steel manual high-pressure self-sealing welded gate valve, designed to ASME B16.34 standards, uses A105 forged carbon steel or 316 stainless steel, developed for high-pressure pipeline systems in petroleum, chemical, and power industries. The valve employs a self-sealing structure that uses medium pressure to dynamically seal the bonnet and body, combined with a bevel gear drive mechanism, maintaining zero-leakage interception performance under Class 1500 (PN250) high-pressure conditions. Its core advantages lie in the high-strength impact resistance of forged steel and the reliability of the self-sealing structure in high-pressure scenarios, suitable for media control (water, steam, oil) at -29℃~425℃.
