Gate Valve 2 Inch Class 600 WCB SS316 Trim
API 600 Certified | Carbon Steel A216 WCB | Flanged RF Ends
Product Overview
The Supreme Valves 2-inch Class 600 Gate Valve is API 600 certified, designed for severe service in oil & gas, petrochemical, and refinery applications across Saudi Arabia and the Middle East. The Carbon Steel ASTM A216 WCB body provides robust pressure containment while the SS316 trim ensures reliable seating in corrosive service.
The flanged ASME B16.5 RF (Raised Face) ends ensure leak-free installation with standard companion flanges. The OS&Y (Outside Stem and Yoke) design with bolted bonnet provides visual position indication and easy maintenance. The flexible wedge disc design accommodates thermal expansion and prevents binding in demanding applications.
With a Class 600 rating of 1440 PSI at ambient temperature, this valve handles high-pressure pipelines, process headers, and steam distribution systems common in Saudi Arabian industrial facilities. Wheel operation provides reliable manual control in plant environments.

Frequently Asked Questions
What is the difference between Class 150 and Class 600 gate valves?
Class 150 valves are rated for maximum 270 PSI at ambient temperature, suitable for general service, water distribution, and low-pressure steam. Class 600 valves are rated for 1440 PSI at ambient temperature (for WCB carbon steel), making them suitable for high-pressure oil and gas pipelines, refinery process units, and petrochemical applications. The Class 600 valve has thicker body walls and robust construction per ASME B16.34 to withstand the higher pressure.
Why use SS316 trim in a carbon steel gate valve?
SS316 trim (where the trim includes the disc, seat ring, stem, and backing nuts) provides superior corrosion and erosion resistance compared to all-carbon steel trim. In oil and gas applications involving crude oil, produced water, or refined products, the stainless steel trim prevents galling, scoring, and seat leakage that commonly occurs with soft steel trim in abrasive or corrosive service.
What does OS&Y mean on a gate valve?
OS&Y stands for Outside Stem and Yoke. This design features the valve stem threads and nut located outside the bonnet, visible when the valve is open. The stem threads engage with a yoke nut in the bonnet, which translates rotational handwheel motion into linear stem travel to raise or lower the wedge disc. The OS&Y design provides easy visual confirmation of valve position (open/closed) without disassembling the valve.
Can this gate valve be used for steam service?
Yes, this Class 600 gate valve is suitable for saturated and superheated steam service up to the pressure-temperature limits defined by ASME B16.34. For WCB carbon steel, the maximum temperature is 425°C (800°F). At 425°C, the Class 600 rating is approximately 570 PSI, which covers most industrial steam distribution requirements.
