ANSI Standard Stainless Steel CF8, CF8M Flanged Float Type Ball Valve
Product introduction:
A Ball Valve is a shut-off valve that rotates a ball with a bore inside it to permit, restrict, and control the flow of liquids, gases, and vapors in a pipe system. The shaft that connects the ball to the operational and controlling mechanism that rotates the ball is mounted against two seats. The fluid is not allowed to pass through the valve when the cross-section of the bore is perpendicular to the area of the flow. The area of the bore that is exposed to the floor determines how much fluid flows through the valve and at what pace. They can be turned manually, with the aid of an actuator, a wrench, or a lever that is manually turned by the operator. To open or close the valve, torque is exerted to move the lever arm by 90 degrees in either a clockwise or counterclockwise direction. The valve is open if the lever arm is perpendicular to the pipe. A closed valve is indicated by the lever arm being perpendicular to the pipe. To meet varied industrial applications, it is available in a variety of designs and characteristics. Depending on the industry in which this valve is used, different norms and specifications apply.
Stainless steel ball valve switch is light and small, and its caliber can be large. It is reliably sealed with simple structure and is easy to be maintain. As the sealing surface and ball surface are always closed and are difficult to be scoured by medium, it is widely used in various industries.

Product features:
1. Ball valves normally with casting manufacturing craft for low pressure and small size unit use, and for high pressure ball valve, normally they are made using a forging process that results in a stronger and more durable valve compared to those made using casting or machining methods.
2. Ball valve can be made from a range of materials that offer excellent corrosion resistance, including stainless steel, alloy steel, and other exotic alloys.
3. Ball valve can provide precise flow control by rotating the ball to either block or allow flow through the valve.
4. Ball valve is easy to operate and require minimal maintenance, making them a popular choice in a wide range of applications.
5. Ball valve is a kind of quick opening and closing valve product.
