310S stainless steel ball valve, stainless steel ball valve

Product Overview

The 310S stainless steel ball valve is also known as the 2520 ball valve. All the components of the valve body, valve cover, valve stem, and ball are cast or forged using austenitic heat-resistant stainless steel 310S (0Cr25Ni20). This material is a high-chromium-nickel austenitic stainless steel, which has excellent corrosion resistance in oxidizing media and good high-temperature mechanical properties. Therefore, it is widely used in heat control components in the chemical industry and aerospace industry at temperatures of around 1100°C, as well as in corrosion-resistant control equipment for post-processing.

Product Features

1. This valve is a full-diameter floating ball valve with a compact structure, a beautiful appearance, and a low flow resistance coefficient.

2. The sealing surface is made of fluoroplastic, and the sealing pair materials are well matched, ensuring a long service life.

3. The ball is closely sealed with the PTFE valve seat, featuring zero leakage. It can automatically compensate for errors caused by wear due to its plastic deformation, achieving good sealing performance and a long service life. To ensure the sealing at the valve stem, a packing box and a cover are added on the valve body.

4. Various pipe flange standards and flange sealing surface types can be selected. Various driving methods such as manual, worm gear drive, electric, pneumatic, and hydraulic can also be used to meet the different needs of users.

Product Application

It is austenitic chromium-nickel stainless steel, with the stainless steel grade being 06Cr25Ni20. Usually, it is also referred to as 2520 duplex stainless steel. The ball valve has reliable sealing, a simple structure, and the sealing surface and the spherical surface are often in a closed state, which is less prone to be eroded by the medium and is easy to operate and maintain. It is suitable for general working media such as water, solvents, oil, gas, acids, and natural gas, and is also applicable to media with harsh working conditions, such as oxygen, * gas, methane, and ethylene, etc. It has been widely used in various industries including petroleum, electronics, chemical engineering, medicine, light textile, food, machinery, construction, nuclear power, etc.
