high pressure gate valve Description
High-pressure gate valves are cut-off valves specially used in high-pressure pipeline systems. They realize medium on-off control through vertically lifting gates. The valve body is usually made of stainless steel (such as 304, 316L) or alloy steel, with high strength, high pressure resistance and corrosion resistance.
Advantages
High-pressure bearing capacity
The valve body structure is strengthened (such as thickened wall thickness) and can work stably in the PN40~PN64 pressure range;
Sealing reliability
The leakage level of the hard seal structure reaches VI level, and the soft seal (such as EPDM) achieves zero leakage;
Corrosion resistance
304/316L stainless steel or special alloy materials resist acid and alkali medium erosion;
Convenient operation
The valve stem adopts a low-friction design (such as thrust bearing support), and the opening and closing torque is reduced by 30%~50%

Applications and industries
Petrochemical
Scenario: High-pressure oil and gas pipelines, acidic media (such as H₂S) cutoff; Reason: Corrosion resistance and high-pressure bearing capacity meet the long-term stability requirements of acidic environments.
Energy and Power
Scenario: Steam pipeline network of thermal power plants (pressure>10MPa); Reason: High temperature and high pressure resistance (such as 550℃) ensures the safe operation of thermal systems.
Pharmaceuticals and Food
Scenario: Sanitary fluid (such as pure water, fermentation liquid) transportation pipelines; Reason: 316L stainless steel meets FDA hygiene standards to avoid medium contamination.
Metallurgy and Mining
Scenario: High-pressure water-coal slurry transportation, slurry control; Reason: Carbide sealing surface has strong wear resistance and is suitable for working conditions containing particle media
