3 Piece Threaded Ball Valve Basic Overview

I. Overview of 3 Piece Threaded Ball Valve:

As the name suggests, stainless steel valves are valves made of stainless steel.

Stainless steel valves are available in increasing material quality, generally including 304 stainless steel, 304L stainless steel, 316 stainless steel, 316L stainless steel, and bidirectional stainless steel.

Stainless steel valves are used in the food and biscuit industry, instant noodle and rice noodle industry, various frozen food dehydration lines, and the glassware industry. They can be used to control the flow of various fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metal, and radioactive media.

Stainless steel valves are widely used in the chemical, petrochemical, oil, papermaking, mining, power generation, liquefied gas, food, pharmaceutical, water supply and drainage, municipal engineering, machinery and equipment support, electronics, and urban construction industries.

Stainless steel valves are control components in pipeline fluid transportation systems. They are used to change the cross-section of the passage and the direction of the medium's flow, performing functions such as diversion, shutoff, regulation, throttling, check, diversion, and overflow 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. Stainless steel 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. Operating pressures range from 0.0013 MPa to ultra-high pressures of 1000 MPa, and operating temperatures range from ultra-low temperatures of -269°C to high temperatures of 1430°C.

Stainless steel valves are typically used in applications where the working medium is somewhat corrosive. The corrosion resistance of any valve material is relatively limited and is affected by many factors. Proper processing and heat treatment during manufacturing can ensure the material's corrosion resistance. However, in concentrated nitric acid with a concentration greater than 98%, no matter what heat treatment process is used, this steel will not exhibit corrosion resistance. Therefore, when selecting valve materials based on the properties of the working medium, it is important to consider the impact of factors such as the medium's concentration, temperature, and the material's heat treatment process on corrosion resistance. Stainless steel valves have become a must-have across various industries, but few domestic valve manufacturers meet international standards. Therefore, before purchasing stainless steel valves, customers must request production and factory certificates for various valves to avoid purchasing substandard products. Currently, stainless steel and sanitary valves that meet international standards primarily come from Japan, Germany, the United States, the United Kingdom, and first-tier cities such as Shanghai. Stainless steel valves are control components in pipeline fluid conveying systems. They are used to change the cross-section of the passageway and the direction of the medium's flow, performing functions such as diversion, shutoff, regulation, throttling, check valves, diversion, and overflow/pressure relief. Valves used for fluid control come in a wide variety of styles and specifications, from the simplest globe valve to the most complex valves used in automated control systems. Valves can be used to control water, steam, oil, gas, slurry, and various corrosive media. The control of valves can adopt a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic, electromagnetic-hydraulic, electric-hydraulic, pneumatic-hydraulic, spur gear, bevel gear drive, etc.; under the action of pressure, temperature or other forms of sensor signals, it can act according to predetermined requirements, or simply open or close without relying on sensor signals. The valve relies on 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.
