Flange-connected ball valve is suitable for Class150～1500, PN1.6～16.0MPa, working temperature -29～180°C (sealing ring is reinforced polytetrafluoroethylene) or -29～300°C (sealing ring is para-polyphenylene) On various pipelines, it is used to cut off or connect the medium in the pipeline. Different materials can be used for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media.

Detailed Description:

The structural design of the flanged copper ball valve absorbs advanced technology at home and abroad. The valve seat adopts elastic sealing structure, which is reliable in sealing and easy to open and close. The valve stem adopts a bottom-mounted structure with an inverted seal. When the valve cavity is abnormally boosted, the valve stem will not be flushed out. It is equipped with a refractory structure that is reliable and has good sealing in the event of a fire. According to the needs of users, it can be equipped with anti-static structure. The 90° switch with hole positioning piece is set, and can be locked as needed to prevent misoperation. DN15～200mm can adopt floating ball structure, and DN150～500mm can adopt fixed ball structure.

Technical Parameters:

1. Nominal diameter: DN15-200

2. Nominal pressure: 0.6MPa-4.0MPa

3. Applicable medium: water, steam, oil, etc.

4. Inspection standard: JB/T9092

5, structure length: GB12221-89

Use occasions:

Flange ball valves are widely used in petroleum refining, long-distance pipelines, chemical, paper, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, occupying a pivotal position in the national economy.
