OMB 810 Forged Steel Gate Valve, 1 Inch, Class 800

The OMB 810 is a robust forged steel gate valve designed for high-pressure applications in industrial settings such as oil and gas, petrochemical, and power generation industries. Manufactured by OMB Valves, an Italian leader in valve technology, this model features a bolted bonnet design with outside screw and yoke (OS&Y) for reliable operation and easy maintenance. Constructed from ASTM A105 carbon steel body with 13% chrome stem and hard-faced disc and seats, it offers excellent resistance to corrosion and wear, ensuring longevity in demanding environments. Key benefits include tight shutoff, low torque operation via the handwheel, and compliance with standards like API 602, ASME B16.34, and BS 5352. Compared to similar products from competitors like Velan or Bonney Forge, the OMB 810 provides superior pressure handling up to 1975 psi at ambient temperatures (commonly rounded to 2000 psi for Class 800), with temperature limits from -29°C to 425°C. Drawbacks may include higher initial cost due to forged construction and the need for periodic stem lubrication. This valve is ideal for isolation duties in pipelines, refineries, and steam systems, offering advantages in space-constrained installations due to its compact design. Based on provided images, this unit appears used with visible wear and residue, but structurally intact, making it suitable for refurbishment or secondary market use.
