Manual Forged Steel Flange Ball Valve

Q347F PN16~PN64 manual forged steel flange ball valve is used on various pipelines of Class150~Class1500, PN16~PN64, JIS10K~JIS20K. It is used to cut off or connect the medium in the pipeline. Different materials can be used separately. In water, steam, oil, liquefied gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing medium, urea and other media.

Product Details

Product Description

The manual forged steel flange ball valve is divided into three parts along the cross section perpendicular to the valve channel axis at the two valve seat parts. The whole valve is symmetrical along the central axis of the valve stem. The forged steel high pressure flange ball valve is mainly used for cutting, Assign and change the direction of media flow.

Features

1. The forging steel high-pressure flange ball valve is made of braided, flexible graphite sealing ring or tetrafluoroolefin sealing ring, which makes the valve stem achieve reliable sealing under certain lubrication conditions.

2. According to the needs, the forged steel high-pressure flange ball valve can be designed as an anti-static structure. A conductive spring is arranged between the ball and the valve stem, the valve stem and the casing to avoid electrostatic ignition and ignite flammable substances to ensure system safety.

3. Various types of sealing sub-types. According to different working conditions, soft seal, hard seal, fireproof seat and other structures can be selected; below DN150 is a float ball type forged steel high pressure flange ball valve, and below DN200 is a fixed ball type.

4. The auxiliary seal structure can be set at the valve seat of the forged steel high-pressure flange ball valve. The grease-filling valve can be installed at the valve seat and the valve stem. It can be temporarily sealed in case of emergency, and the valve stem can be lengthened as needed to be buried. place.

Forged steel flange ball valves are an important part of long-distance pipeline transportation and urban gas pipeline systems mainly used for oil and natural gas. Forged steel high-pressure flange ball valve has the unique feature of long-distance pipeline valve, which is designed with good ability to withstand pipeline stress. Due to the special nature of pipeline transportation, the forged steel high pressure flange ball valve needs good safety, reliability and long service life. Therefore, special attention must be paid to the structural design of the forged steel high pressure flange ball valve. Industry standard. Unscrew the removal device to check for leaks in the seat, or drain the retentate in the chamber to reduce the unilateral contamination of the valve. In general, the material used for forged steel high-pressure flange ball valves must have good corrosion resistance and ensure stable sealing performance. In the case of damage to the seal ring, the forged steel high-pressure flange ball valve should also have a certain degree of sealing, so as to be able to provide emergency rescue in the event of a leak. Forged steel high-pressure flange ball valves require good resistance to vulcanization in addition to corrosion resistance, and must be excellent in fireproof and antistatic properties.
