Types And Illustrations Of Sanitary Valves

Sanitary Valve are the most common components we see on-site. Three-impulse control of drum liquid level and boiler combustion control all rely on valve opening and closing to control the object. The goal of our algorithms is to control valve opening and closing, thereby achieving automatic control. Valves have a wide range of uses, and therefore play a significant role. For example, in power plants, valves control the operation of boilers and steam turbines. In petroleum and chemical production, valves also play a crucial role in ensuring the proper operation of all production equipment and processes. Despite this, valves are often overlooked compared to other products. For example, when installing machinery and equipment, people often focus on key components such as compressors, high-pressure vessels, and boilers. This practice can reduce overall production efficiency, lead to production halts, or cause various other accidents. Therefore, it is necessary to understand and appreciate valves. Valves are classified by various types, and their definitions vary widely. Some are categorized by application (e.g., chemical, petroleum, power plants), by medium (e.g., steam, air valves), by material (e.g., cast iron, cast steel, forged steel), by connection type (e.g., internal thread, flanged valves), and by temperature (e.g., low-temperature, high-temperature).

Currently, valves are generally classified by pressure and structure. Specifically, they are categorized by nominal pressure: ≤ 10 MPa for low-pressure valves, 10 MPa for medium-pressure valves, 10 MPa or higher for high-pressure valves, and 100 MPa or higher for ultra-high-pressure valves.

The main structural classifications include:

Plug valves, gate valves, globe valves, and ball valves—used to open or close the flow of media in pipelines.

Check valves (including foot valves)—used to automatically prevent backflow of media in pipelines.

Throttle valves—used to regulate the flow of media in pipelines.

Butterfly valves—used to open or close the flow of media in pipelines. They can also be used for regulating functions. Safety valves—used in boilers, containers, equipment, and pipelines—automatically relieve excess pressure when the medium pressure exceeds a specified value, ensuring safe production operations.
Pressure reducing valves—used to automatically reduce the medium pressure within pipelines and equipment. This system creates resistance as the medium passes through the gap between the valve discs, resulting in pressure loss and pressure reduction.
Steam traps—used in steam pipelines to automatically remove condensate, preventing steam loss or leakage.
