The Cast Steel OS&Y Gate Valve Class 300 is a robust isolation valve engineered for high-pressure and high-temperature service in demanding industrial applications. Constructed from ASTM A216 WCB cast carbon steel, it provides excellent mechanical strength and durability under severe operating conditions.
The Outside Screw and Yoke (OS&Y) design keeps the stem threads external to the process media, offering a clear visual indication of valve position and ensuring long service life. Hard-faced seating surfaces deliver enhanced wear resistance and tight sealing performance even under severe operating cycles.
Designed and manufactured in accordance with API 600 / API 6D standards and pressure-rated to ASME B16.34, this valve guarantees reliable performance and full compliance with international specifications. The graphite gaskets and packing ensure leak-free sealing at elevated temperatures, while the stainless steel stem provides corrosion resistance and smooth operation.
Ideal for use in refineries, power generation, petrochemical plants, and general industrial services, this valve combines long-lasting durability with ease of maintenance.
