Product Range
OS &Y Type Bolted Bonnet Rising Spindle Flanged end
OS & Y (Outside Screw & Yoke) Type Bolted Bonnet Rising Spindle Flanged End valves are designed for safe, reliable, and visible flow regulation in industrial piping systems. The rising spindle mechanism ensures clear position indication, allowing operators to verify whether the valve is open or closed. This design not only enhances operational safety but also supports easy maintenance and inspection. The bolted bonnet construction ensures secure sealing under varying pressure and temperature conditions, making it suitable for critical applications.
Reliable OS&Y Bolted Bonnet Flanged End Industrial Valve
These valves are widely used in industries such as oil & gas, petrochemical, power generation, chemical processing, and water treatment. The flanged end connection enables strong pipeline integration, providing a robust and leak-free setup even in high-pressure systems. Due to their excellent sealing capability, these valves minimize the risk of leakage and help maintain system reliability over long-term operation.
They are suitable for both on-off and throttling services, making them versatile for different process requirements. The OS & Y configuration keeps the stem threads outside the fluid stream, preventing corrosion and wear, thus ensuring longer service life. This design also significantly reduces friction during valve operation, allowing for smooth movement of the spindle. The rising stem feature provides a direct visual indicator of valve position, ensuring clarity and safety in manual operation. These valves are engineered to operate efficiently in demanding conditions, supporting high-performance industrial systems. Constructed from high-quality materials and precision-engineered components, these valves deliver exceptional durability and performance.
