Q61N High Pressure Welding Ball Valve
The Q61N high-pressure welded ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the axis of the valve stem. It is mainly used to cut off or connect the medium in a pipeline, and can also be used for fluid regulation and control. In pipelines, high-pressure welded ball valves are mainly used for cutting off, distributing, and changing the flow direction of the medium. It requires only a 90-degree rotation and a very small torque to achieve a tight seal.

The Q61N high-pressure welded ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the axis of the valve stem. It is mainly used to cut off or connect the medium in a pipeline, and can also be used for fluid regulation and control. High-pressure welded ball valves are mainly used in pipelines for cutting off, distributing, and changing the flow direction of the medium. They require only a 90-degree rotation and a very small torque to achieve a tight seal. Ball valves are best suited for on/off and shut-off applications. The main characteristics of welded ball valves are their compact structure, reliable sealing, هيكل بسيط, and convenient maintenance. The sealing surface and the ball are always in a closed state, making them less susceptible to erosion by the medium. They are easy to operate and maintain, suitable for general working media such as water, solvents, acids, and natural gas, and also suitable for media with harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. They are widely used in various industries. The valve body of a high-pressure welded ball valve can be integral or modular.
Q61N High Pressure Welding Ball Valve Main Advantages
1. مقاومة منخفضة للسوائل: Full-bore ball valves have virtually no flow resistance.
2. Simple structure, small size, and light weight.
3. Tight and reliable. It has two sealing surfaces, and currently, various plastics are widely used as sealing materials for ball valves, resulting in good sealing performance and achieving a complete seal. It is also widely used in vacuum systems.
4. Easy operation and rapid opening and closing: Only a 90° rotation is needed to go from fully open to fully closed, facilitating remote control.
5. Easy maintenance: The ball valve has a simple structure, and the sealing rings are generally movable, making disassembly and replacement convenient.
6. When fully open or fully closed, the sealing surfaces of the ball and seat are isolated from the medium, preventing erosion of the valve sealing surfaces during medium flow.
7. Wide range of applications: Suitable for diameters ranging from a few millimeters to several meters, and for applications from high vacuum to high pressure.
Q61N High Pressure Welding Ball Valve Main Features
1. All components of this product are forged.
2. A bottom-mounted valve stem with a reverse sealing structure ensures reliable sealing at the packing and prevents the valve stem from detaching.
3. An embedded valve seat is used. An O-ring is installed on the back of the valve seat to ensure no media leakage.
