Valves are pipeline accessories used to open and close pipelines

Valves are pipeline accessories used to open and close pipelines, control the flow direction, and regulate and control the parameters (temperature, pressure, and flow) of the transport medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on.

The valve is a control component in the fluid delivery system and has functions such as cut-off, regulation, diversion, reverse flow, pressure regulation, diversion, or pressure relief. Valves used in fluid control systems, ranging from the simplest shut-off valves to various valves used in highly sophisticated automatic control systems, are quite diverse in variety and size.

Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurries, oils, liquid metals, and radioactive media. According to the material, the valve can be divided into cast iron valve, cast steel valve, stainless steel valve, fully welded ball valve, metal seated ball valve, automatic recirculation valve, plastic valve, and non-standard customized valve.

A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. It is a device that allows the flow of a medium (liquid, gas, powder) in a piping and equipment, and stops and controls its flow.

The valve is the control component in the pipeline fluid delivery system and is used to change the passage section and the direction of the medium flow. It has functions such as diversion, cut-off, throttling, non-return, diversion, or pressure relief. Valves for fluid control, ranging from the simplest stop valve to various valves used in highly complex automatic control systems, are available in a wide range of sizes and sizes. The valve's nominal diameter ranges from extremely small gauge valves up to 10m in diameter. Industrial pipeline valves. It can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals, and radioactive fluids. The working pressure of the valve can be from ultra high pressure from 0.0013MPa to 1000MPa, and the working temperature can be C-270°C to a high temperature of 1430°C.

Valve control can use a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electro-hydraulic, electro-hydraulic, gas-liquid, spur, bevel gear drive, etc.; can be in pressure, temperature Or other forms of sensory signals, operate according to predetermined requirements, or simply open or close without relying on sensing signals, the valve relies on a drive or automatic mechanism to make the opening and closing parts move up and down, slip, swing or turn Movement, thereby changing the size of its flow area to achieve its control function.
