Flanged Resilient OS&Y Gate Valve is mainly used for fluid control in pipeline systems and can effectively open or close the flow in the pipeline. It operates the gate by rotating the valve stem. OS&Y stands for "Outside Screw and Yoke", which means the valve stem is externally designed for easy operation and maintenance. The resilient seat sealing technology ensures that the valve has better sealing when opening and closing to prevent leakage. This valve is commonly used in fire protection systems, water treatment systems and water supply pipelines, and is particularly suitable for applications that require high reliability and durability. Its flange connection method facilitates quick docking with other pipeline components and simplifies installation.

Flanged Resilient OS&Y Gate Valve is a premium quality industrial valve designed for applications requiring tight shutoff and reliable service in various pipeline systems. The "OS&Y" stands for Outside Stem and Yoke, indicating that the stem is outside the valve body, which is a feature that allows for visual confirmation of the valve's position. This gate valve is constructed with a resilient wedge gate, which ensures a tight seal and prevents leakage. The flanged ends are designed to connect easily with standard flange dimensions, making it compatible with a wide range of piping systems. The valve is available in various materials, including carbon steel, stainless steel, and alloy steel, to suit different media and temperature requirements. The robust design and construction of this valve make it ideal for use in water treatment plants, oil refineries, power generation facilities, and other industrial applications where durability and performance are critical.
The Flanged Resilient OS&Y Gate Valve boasts several key features that set it apart in the market. Firstly, its resilient wedge gate design provides a bubble-tight seal, ensuring no leakage even under high-pressure conditions. The outside stem and yoke design offer a clear indication of the valve's open or closed position, enhancing safety and operational efficiency. The valve is engineered with a rising stem, which prevents the stem from rotating, thus maintaining the position of the gate and ensuring long-term performance. The flanged ends are designed to meet international standards such as ANSI, DIN, or BS, ensuring compatibility with existing pipeline systems. The valve is also designed to be easily maintained, with the ability to replace the gate and stem packing without removing the valve from the pipeline. The durable construction materials ensure resistance to corrosion, erosion, and high temperatures, making it suitable for a wide range of applications.
The Flanged Resilient OS&Y Gate Valve is widely used in various industries where reliable shutoff and long-term durability are essential. It is commonly found in water treatment plants for controlling the flow of water and chemicals. In oil refineries, it is used for isolating process lines and equipment during maintenance or in emergency shutdown situations. The valve is also used in power generation facilities for managing the flow of steam and water in cooling systems. Additionally, it is utilized in chemical processing plants for handling corrosive fluids and in gas transmission lines for controlling the flow of natural gas. Due to its robust design and ability to withstand high pressures and temperatures, the valve is suitable for both onshore and offshore applications, making it a versatile choice for many industrial sectors.
