How To Choose The Right Stainless Steel Valve For The Piping System? These Three Points Are Very Important!

In various pipeline systems, valves are always an important existence. Valves can control the fluidity of the medium in the pipeline and equipment, and can control the amount of flow. So how do you choose a suitable 2 Piece Threaded Ball Valve for the pipeline system?

1. Look at the purpose requirements

There are many types of piping valves, which can be classified according to structural characteristics, purpose, drive mode, pressure bearing capacity, nominal diameter, etc. In order to facilitate the purchase, the most common classification method for customers is to look at the purpose of the valve. Pipeline valves can be divided into opening and closing, throttling, distribution, check, safety valves and special purpose stainless steel valves according to their purpose.

2. Look at the working conditions

Valves are widely used. There are differences in the pressure bearing of the valve sealing surface under various working conditions. Some are even vacuum, and some are ultra-high pressure. There are often extrusion and shear forces on the sealing surface. The ambient temperature will also vary greatly, from -270 to as high as 800 degrees Celsius. When valves are used in the pipeline system of the chemical industry, the corrosiveness of the medium must also be considered. There are valves made specifically for non-corrosive medium fluids, various strong acid and strong alkali media, and the wear of medium particles on valves.

3. Look at the medium fluid

Valves can be used in various pipeline systems and various media controls. The most common ones are fluid media, solid media, gas fluid media, etc. Therefore, looking at the fluid medium is also an important reference item when purchasing valves.

Stainless steel valves used in different types of uses and different working environments have different structures and materials. For example, in pipeline systems with an ambient temperature of more than 300°C, valves are made of high-temperature resistant heat-resistant steel.
