Neway 6 Inch Class 150 Duplex Stainless Steel Gate Valve Fig. 3406

The Neway 6 Inch Class 150 Gate Valve, constructed from ASTM A995 Grade 4A duplex stainless steel, is designed for reliable shut-off in demanding industrial applications such as oil and gas, petrochemical, and marine environments. This valve features a bolted bonnet, outside screw and yoke (OS&Y) design, and flexible wedge gate for enhanced sealing under varying pressures and temperatures. Key benefits include excellent corrosion resistance due to the duplex material, which outperforms standard stainless steels in chloride-rich environments, reducing the risk of stress corrosion cracking. It offers low maintenance, tight shut-off, and compatibility with a wide range of fluids, including seawater and aggressive chemicals. Drawbacks may include higher initial cost compared to carbon steel valves and the need for proper torque application during installation to avoid damage. Compared to similar products from competitors like Velan or Crane, the Neway model provides superior durability in harsh conditions with a proven track record of longevity. Applications include pipeline isolation, process control, and high-pressure systems up to Class 150 ratings. This unit appears new or surplus, stored in original crating, with no visible wear, making it ideal for immediate deployment in critical infrastructure.
