Gate Valve OS&Y Bolted Bonnet Design Screwed End / Socket Weld

The Gate Valve OS&Y (Outside Screw & Yoke) Bolted Bonnet Design from Sparkey Valve and Fitting Pvt. Ltd. is engineered for reliable isolation and control of fluid flow in industrial pipelines. Its OS&Y design ensures that the valve stem rises and lowers with the gate, providing visual indication of the valve’s position and simplifying maintenance checks. The bolted bonnet design offers enhanced structural integrity and pressure containment. 

Corrosion-Resistant Gate Valve EnsuresLong-Term Reliability in Pipelines

The valve is available with screwed end or socket weld connections, allowing flexible integration into various pipeline systems. The threaded or welded ends provide secure, leak-proof connections while maintaining compactness and ease of installation. This versatility makes it ideal for systems where flanged connections are not feasible or where space is limited.

The valve body and gate are precision-engineered to provide smooth operation and tight shut-off, minimizing leakage. The robust construction also ensures resistance to corrosion, wear, and high-temperature conditions, making it suitable for demanding industrial applications. These valves find extensive applications across water treatment, oil and gas pipelines, chemical and petrochemical plants, power generation, and industrial process lines. Their reliable isolation capability allows operators to safely perform maintenance, regulate flow, and protect downstream equipment. The OS&Y design enhances operational safety by providing clear visual indication of whether the valve is open or closed.
