Product Range
OS & Y Type Bolted Bonnet Rising Spindle Pn40
OS & Y Type Bolted Bonnet Rising Spindle PN40 Valves are engineered for reliable performance in high-pressure industrial applications. The Outside Screw and Yoke (OS&Y) design ensures clear visibility of valve position, making it easy to determine whether the valve is open or closed. With a bolted bonnet and PN40 pressure rating, these valves offer superior strength, robust sealing, and long-term reliability under demanding operating conditions. These valves are widely used in oil & gas, petrochemical, power generation, and other industries where safety and operational precision are crucial.
High-Pressure OS&Y Rising Spindle PN40 Valve for Pipelines
The valve is available with manual, gear-operated, and automated actuation options to suit different applications and system requirements. It is suitable for both on-off operation and throttling service, ensuring precise flow regulation while maintaining high reliability. The rising spindle facilitates easy maintenance and clear operational status, enhancing safety in critical systems.
The bolted bonnet assembly enhances sealing integrity, making the valve suitable for high-pressure and high-temperature environments. Manufactured from high-quality carbon steel, alloy steel, or stainless steel, the valve components provide excellent resistance to corrosion, chemical exposure, and mechanical stress. The PN40 pressure rating indicates that the valve is capable of withstanding pressures up to 40 bar, making it ideal for heavy-duty industrial applications. Maintenance is simplified due to the OS&Y design, which allows operators to monitor and access the spindle without dismantling the valve from the pipeline. Their commitment to innovation and quality makes them a trusted partner in industrial flow control solutions.
