Stainless Steel Ball Valve And Basic Principles Of Stainless Steel Ball Valve

The Stainless Steel Ball Valve is a widely used valve, primarily used for analog flow control of liquid, gas, and air pipeline media, employing AI control. Electric valves can also be used for two-position on/off control in large valves and air system control. Let's take a look at the principles of the Stainless Steel Ball Valve.

The Stainless Steel Ball Valve typically consists of an electric actuator connected to a valve, which, after installation and commissioning, becomes a motorized valve. The Stainless Steel Ball Valve uses electrical energy to activate the electric actuator, driving the valve to open or close, thereby achieving the purpose of opening or closing the pipeline medium.

Operating Characteristics of the Stainless Steel Ball Valve: Electric valves are typically driven by motors and are relatively resistant to voltage surges. Solenoid valves operate quickly, opening and closing, and are generally used for low flow and pressure applications requiring a high switching frequency. Electric valves, on the other hand, offer controllable valve openings, including open, closed, and partially open/closed positions. This allows for flow control in pipelines, a requirement that cannot be met by solenoid valves.

The Stainless Steel Ball Valve evolved from the plug valve. It shares the same 90-degree poppet action, but some Stainless Steel Ball Valve differ in that the plug body is spherical and has a circular through-hole or channel running through its axis.

The relative proportions of the spherical surface and the channel opening are such that when the ball is rotated 90 degrees, the inlet and outlet should assume a completely spherical shape, thus blocking the flow. Electric plastic ball valves achieve a tight shutoff with just a 90-degree rotation and minimal torque. The identical valve body provides a low-resistance, straight-through flow path for the medium. While ball valves are generally considered best suited for direct opening and closing, recent developments have enabled them to be designed for throttling and flow control. The key features of ball valves are their exceptionally compact design and ease of operation, repair, and maintenance. They are suitable for common working media such as water, solvents, acids, and natural gas, as well as for harsh working media such as oxygen, hydrogen peroxide, methane, and ethylene.

The ball valve body can be either one-piece or modular. Ball valves are lightweight and compact, can be manufactured in large diameters, offer reliable sealing, and are particularly simple to maintain. The sealing surface and spherical surface are typically closed, making them less susceptible to erosion by the medium. They are widely used in various industries. Electric plastic ball valves and plug valves are similar valves, except that the closing element is a sphere that rotates around the centerline of the valve body to open and close.

Ball valves are primarily used in pipelines to cut off, distribute, and change the flow direction of media. Electric plastic ball valves are a new type of valve that has been widely adopted in recent years. They offer the following advantages: 1. Low fluid resistance, with a resistance coefficient comparable to that of a pipe section of the same length. 2. Simple structure, compact size, and light weight. 3. Tight and reliable. Currently, ball valves are widely used in vacuum systems, with plastic being the most common sealing surface material. 4. They are extremely easy to operate, opening and closing quickly, and only require a 90° rotation from fully open to fully closed, facilitating remote control. 5. Easy maintenance, the ball valve has a simple structure, and the sealing ring is generally movable, so disassembly and replacement are relatively convenient and quick.
