Globe Valve 1 Inch Class 1500 API 602

The Supreme Valves 1 inch Class 1500 Globe Valve is API 602 certified for compact steel valves in petroleum and natural gas service. Designed for severe applications in oil refineries, petrochemical plants, and high-pressure steam systems across Saudi Arabia and the Middle East.

The Carbon Steel A216 WCB body provides robust pressure containment while the Stainless Steel SS316 trim ensures reliable seating and stem integrity in corrosive service. The OS&Y (Outside Stem and Yoke) design with bolted bonnet offers easy maintenance access without disturbing the piping system.

Socket Weld ends per ASME B16.11 provide a permanent, high-integrity connection suitable for the Class 1500 pressure rating. This valve is commonly specified for Saudi Arabian projects requiring API 602 compliance for upstream oil & gas, refining, and power generation applications.

What is API 602 and why is it important for globe valves?

API 602 is the American Petroleum Institute standard for 'Compact Steel Gate Valves - Flanged, Threaded, Welding, and Extended-Body Valves.' This standard specifically covers DN 4 (NPS 1/8) through DN 50 (NPS 2) steel valves for use in petroleum and natural gas industry applications. API 602 valves are designed for high-pressure, high-temperature service with requirements for body wall thickness, stem material, and pressure-temperature ratings that exceed general-purpose valve standards. For Saudi Arabian oil and gas projects, API 602 certification is often a mandatory procurement specification.

What does Class 1500 pressure rating mean?

Class 1500 valves are rated for a maximum working pressure of 370 bar (5365 PSI) at ambient temperature for carbon steel. The pressure rating follows ASME B16.34 which defines pressure-temperature relationships for steel valves. At elevated temperatures, the allowable pressure decreases. For 1 inch Class 1500 globe valves in steam service at 425°C, the rating reduces to approximately 155 bar. This makes Class 1500 suitable for high-pressure steam distribution, boiler outlets, and oil field gathering lines in Saudi Arabian and Middle Eastern projects.

What is the difference between Socket Weld and Threaded ends?

Socket Weld (SW) ends per ASME B16.11 provide a higher pressure rating than NPT threaded ends and are preferred for high-pressure applications. The pipe slides into the socket and is fillet welded around the circumference, creating a strong, leak-free joint suitable for severe service. Threaded ends (NPT) per ANSI/ASME B1.20.1 are easier to install and remove but are limited to lower pressure ratings. For Class 1500 applications in Saudi Arabian oil and gas, Socket Weld is the standard specification.

What is the typical Production schedule for API 602 Class 1500 globe valves?

Standard API 602 Class 1500 globe valves ship within 2-3 weeks from our Ahmedabad facility. For projects in Saudi Arabia requiring batch quantities, delivery to Dammam or Jeddah port takes 3-4 weeks by sea freight. We provide complete documentation including mill test certificates per ASTM A106/A216, API 598 inspection reports, and material traceability documents required for Saudi Aramco and SABIC procurement specifications.
