Covna DN150 6 Inch 2 Way Double Flange Type Cast Steel Lever Operated Ball Valve Brass/Stainless

•Structure and Design:

Compact Structure: Ball valves are designed to be compact and occupy minimal space.
90-Degree Operation: The ball, as the closing element, is rotated 90 degrees around the valve axis by the valve stem for quick and easy operation.
Reliable Sealing: The sealing surface of the ball valve is always in contact with the ball when closed, ensuring complete sealing and not easily eroded by the media.

Performance Advantages:

Low Fluid Resistance: Ball valves have the lowest fluid resistance among all valve types, especially full-bore ball valves, where the flow resistance is almost zero.
Wear Resistance: The valve core and sealing ring of hard-seated ball valves are made of special materials, such as alloy steel, which have excellent wear resistance.
Strong Sealing Performance: Ball valves have reliable sealing performance and are widely used in various media, including corrosive media and low-boiling-point liquids.
Non-erosive to High-speed Media: When fully open or closed, the sealing surfaces of the ball and valve seat are isolated from the media, so high-speed media passing through the valve does not cause erosion of the sealing surfaces.
Quick Opening and Closing: Ball valves can achieve rapid opening and closing, with some structures achieving an opening and closing time of only 0.05 to 0.1 seconds, facilitating automatic control.

Application Range:

Widespread Application: Ball valves are widely used in industries such as petroleum refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, power, municipalities, steel, water supply systems, and wastewater treatment.
Versatile Media Compatibility: Ball valves are suitable for various media, including water, solvents, acids, natural gas, oxygen, hydrogen peroxide, methane, ethylene, and more.

Operation and Maintenance:

Easy Operation: Ball valves require only a 90° rotation from fully open to fully closed, making them easy to operate and control.
Convenient Maintenance: Ball valves have a simple structure, and the sealing ring is often a removable part, facilitating disassembly and replacement.

In summary, ball valves are indispensable fluid control devices in numerous industries due to their compact structure, superior performance, wide application range, and convenient operation and maintenance.
