2-PC Flanged Ball Valve

Two-piece flanged ball valve is a kind of industrial valve with two-component bolted structure, connected to the pipeline through the flange interface, combining ease of maintenance and high sealing, its core features are as follows:

Advantages

Maintenance costs reduced by 70%

Modular design makes seal replacement 3 times more efficient.

Long service life

Hardened ball (surface coated with chromium carbide) has more than 3 times the wear life of ordinary valves.

Zero Leakage Guarantee

Soft seal leakage rating up to API 598 Class VI (leakage rate ≤ 10-⁶ mbar-L/s).

Safety redundancy design

Anti-static structure (ball-stem resistance <10Ω);

Valve cavity overpressure automatic relief (some models equipped with pressure relief hole).

 

2-PC Flanged Ball Valve

 

Features

Rapid Maintainability

Seat/ball can be replaced by removing the secondary bonnet without disconnecting the pipeline.

Low flow resistance design

Full bore structure flow resistance coefficient ≤ 0.08, flow loss close to zero.

Wide range adaptability

Temperature range: -196℃ (LNG) ~ 550℃ (steam);

Applicable media: water, oil, acid and alkali liquids, oxygen and particulate ash-containing slag.

Fire and explosion-proof safety

All-metal hard seal models are certified by API 607, and can still be cut off in emergency after the soft seal melts.

Applications

• Petrochemical: sulfur-containing natural gas pipeline, catalytic cracking high temperature oil and gas (≤550 ℃);
• Food and pharmaceutical: aseptic fluid control (316L material + sanitary polishing);
• Energy and Power Energy and power: boiler steam piping, gas turbine fuel conditioning;
• Environmental protection and water treatment: sewage conveyance, seawater desalination system.
