**产品概述**
**本产品** 整体锻钢阀体 气动智能执行系统 高压专用密封设计 工业级安全防护 driven by a quarter-turn pneumatic actuator. Specially designed for high-pressure conditions Class600 to 2500, it features high pressure resistance, reliable sealing, fast operation and high automation. In strict compliance with API 6D, ASME B16.34 and API 607 fire-safe standards, it is widely used in high-pressure and flammable-explosive pipelines such as oil & gas exploitation, natural gas gathering, petrochemical industry and power station high-pressure systems for remote automatic on-off control.
**主要特点**
1. Integral Forged Steel Body
The valve body is integrally forged from A105, F304, F316 forged steel, with dense material free of casting blowholes and sand defects. Its mechanical strength is much higher than cast steel valves, with excellent resistance to high-pressure impact and alternating stress. It can stably adapt to full high-pressure ratings Class600/900/1500/2500 without deformation or leakage under long-term high pressure.
2. Pneumatic Intelligent Actuation System
Equipped with a special rack-and-pinion pneumatic actuator, supporting bothdouble acting and single acting spring return (fail-safe) modes, working stably at 0.4～0.8MPa air supply pressure. It can be equipped with solenoid valve, limit switch, valve positioner and other accessories to realize remote on-off control and 4-20mA regulation control, with fast opening and closing response, suitable for automatic high-pressure pipe network systems.
3. High-Pressure Special Sealing Design
Adopting floating/fixed ball high-pressure sealing structure, the seat is made of metal hard seal or reinforced flexible graphite seal with medium self-energized sealing feature. The higher the pressure, the more reliable the sealing, realizing bidirectional zero leakage. The stem adopts anti-blowout structure with multi-layer high-pressure packing seal, completely eliminating high-pressure medium external leakage.
4. Industrial-Grade Safety Protection
Built-in anti-static structure to avoid static accumulation during operation of flammable-explosive media. The overall structure meets API 607 fire-safe standard, maintaining effective sealing under fire conditions. Full bore/reduced bore is optional, with low flow resistance and non-clogging, suitable for high-pressure media with a small amount of impurities.
**应用领域**
Oil & gas wellheads, high-pressure gathering stations, natural gas long-distance high-pressure pipelines
Refinery hydrogenation units, chemical high-pressure process medium pipelines
Power station boiler high-pressure feedwater and high-temperature steam systems
Oilfield water injection wellheads, high-pressure fluid transmission systems
Natural gas gate stations, urban high-pressure gas pipe networks
产品概述
This Pneumatic High Pressure 气动智能执行系统 is based on an工业级安全防护, which lays a solid foundation for operation under high-pressure conditions and completely solves the pain points of ordinary cast steel valves such as easy deformation and leakage under high pressure. Equipped with a pneumatic intelligent actuation system, it realizes remote automatic control and adapts to the efficient operation and maintenance needs of high-pressure pipe networks.
With bidirectional zero-leakage sealing, API 607 fire and anti-static safety features, the product strictly complies with international industrial standards, covering full high-pressure ratings and various harsh medium conditions. It is a special and reliable choice for on-off control of high-pressure pipelines in oil & gas, petrochemical, power station and other industries, balancing safety, durability and automatic adaptability.
