Product Overview
This Pneumatic High Pressure Ball Valve is designed for Class150~Class2500 (PN20~PN420) ultra-high pressure working conditions, with an integral forged steel valve body and heavy-duty pneumatic actuator as the core. The full series is equipped with GB/ANSI high pressure flanged connection as standard. It drives the ball to rotate 90° pneumatically to realize fast on-off, emergency shut-off and flow regulation of high-pressure pipelines, and can be seamlessly connected to DCS/PLC automatic control systems, with fast switching, pressure and impact resistance, safety and explosion-proof performance.
Available in full sizes DN15–DN400, it strictly complies with global high pressure valve standards including GB, API and ANSI, and is widely used in ultra-high pressure industrial scenarios such as oil and gas wellheads, refineries, power plants, high pressure water treatment, and hydrogen energy storage and transportation.
Key Features
-
Ultra-High Pressure Forged Steel Valve Body
The valve body is integrally formed from A105, F304/F316 forged steel, with wall thickness reinforced according to the maximum Class2500 pressure rating, 100% non-destructive pressure testing. ensuring stable opening and closing under ultra-high pressure.
-
Heavy-Duty Pneumatic Actuator
Equipped with high pressure special pneumatic actuator, full coverage of double acting / single acting spring return (fail-safe type), suitable for 0.4-1.0MPa air supply, the fastest switching time 0.3s. Can be matched with explosion-proof solenoid valve, valve positioner and other accessories, standard IP67 protection, optional ExdⅡBT4/CT4 explosion-proof grade.
-
High Pressure Special Sealing, Bidirectional Zero Leakage
Two sealing options: soft seal type with reinforced PEEK/PPL seat, suitable for medium and high pressure within Class1500, reaching Class VI zero leakage; metal hard seal type overlaid with Stellite/tungsten carbide, resistant to high pressure erosion and high temperature, full pressure coverage from Class150 to Class2500.
-
Standard High Pressure Flanged Connection
The full series only adopts GB/ANSI high pressure flanged connection, RF face for Class150~Class600, RTJ ring joint face for Class900~Class2500. It can be directly connected with the same standard high pressure pipeline, with reliable sealing and convenient disassembly and maintenance.
-
Multiple Safety Structures
Standard equipped with anti-static, blow-out proof stem, API 607 fire-safe structure, high pressure emergency grease injection port at valve seat and stem, and body cavity automatic pressure relief structure, to ensure the operation safety of ultra-high pressure pipelines.
