Sanitary Valve primarily refers to a device installed in a pipeline to control flow, or a device installed in a pressure pipeline to control water flow.
A valve is a control component in a fluid conveying system, performing functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion, or overflow and pressure relief. Valves used in fluid control systems come in a wide variety of types and specifications, from simple stop valves to highly complex valves used in automatic control systems. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media.
A valve is a device used to control the direction, pressure, and flow of fluids in a fluid system. A valve enables or stops the flow of media (liquids, gases, powders) within piping and equipment, and can control their flow. A valve is a control component in a pipeline fluid conveying system, used to change the cross-section of the passage and the direction of the medium's flow, performing functions such as diversion, shutoff, throttling, check valves, diversion, or overflow and pressure relief. Valves used for fluid control come in a wide variety of types and specifications, from simple globe valves to valves used in highly complex automatic control systems. Their nominal diameters range from tiny instrument valves to valves for industrial pipelines up to 10 meters in diameter. Valves can be used to control the flow of various fluids, including water, steam, oil, gas, slurry, various corrosive media, liquid metal, and radioactive fluids. Their operating pressures range from 0.0013 MPa to ultra-high pressures of 1000 MPa, and their operating temperatures extend from -269°C to 1430°C. Valves can be controlled by a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, electro-hydraulic, gas-hydraulic, spur gear, bevel gear drive, etc.; they can act according to predetermined requirements under the action of pressure, temperature or other forms of sensor signals, or simply open or close without relying on sensor signals. The valve relies on a drive or automatic mechanism to make the opening and closing parts move up and down, slide, swing or rotate, thereby changing the size of its flow area to achieve its control function.
