Stainless Steel Casting Industrial Manual High Platform 2PC Flange Ball Valve with Handle

Classification:

A valve is a device used to control the flow of fluids such as liquids, gases, and powdery solids. It can control the flow of fluid by opening or closing, or control the pressure of fluid by adjusting the opening of the valve. Valves are widely used in various industries, including chemical, petroleum, natural gas, water treatment, electricity and other fields.

The main components of the valve include valve body, valve cover, valve core, valve seat, sealing ring, etc. The valve body and valve cover are usually made of cast iron, stainless steel, copper alloy and other materials to withstand the pressure of the fluid. The valve core and the valve seat play a role in controlling the flow of the fluid by moving the position of the valve core to change the passage of the fluid. The sealing ring is used to ensure the sealing performance of the valve and prevent the leakage of fluid.

Valve according to its use can be divided into manual valve and automatic valve two categories. Manual valve requires manual adjustment, usually by rotation, push-pull and other ways of operation, suitable for small flow, small pressure occasions. The automatic valve relies on electric, gas, liquid and other energy sources to realize automatic adjustment. It can automatically open and close or adjust the opening of the valve according to the preset control signal. It is suitable for large flow and high pressure occasions.

There are many kinds of valves, which can be divided into globe valves, gate valves, ball valves, butterfly valves, regulating valves, etc. according to their structural forms. Valve is mainly used to cut off the fluid channel, often used to close or open the fluid pipeline. The gate valve controls the passage of the fluid through the up and down movement of the gate plate, which is often used to adjust the fluid. The ball valve controls the passage of the fluid through the rotation of the ball, and has the characteristics of fast opening and closing, reliable sealing. Butterfly valve is through the rotation of the butterfly plate to control the fluid channel, suitable for large flow, low pressure occasions. The regulating valve controls the opening of the fluid by adjusting the position of the spool, which is suitable for precise control of the fluid flow and pressure.

Valves play a vital role in industrial production. They can control the flow of fluids and ensure the safety, stability and stability of the production process * *. The selection and use of the valve needs to be determined according to the specific process requirements and fluid properties. At the same time, it is necessary to pay attention to the maintenance of the valve, and regularly repair and replace it to ensure the normal operation of the valve. The valve industry is also constantly developing and innovating, constantly improving in materials, design, manufacturing and other aspects to meet the needs of different industries.
