American Standard Swing Check Valve ANSI Class 150 300 600 Cast Steel Forged Steel China Manufacturer

Convenient maintenance and cost optimization

Convenient maintenance and cost optimization
01
The modular structure supports online replacement of valve discs and seals, reducing maintenance downtime by 50% and standardizing parts to reduce spare parts inventory pressure.
02
Welding or flange connection methods are flexible and optional to avoid leakage hazards and reduce installation and maintenance costs.

Corrosion resistance and long lifespan

Corrosion resistance and long lifespan
01
The valve body is made of high-strength materials such as chromium molybdenum steel and stainless steel, and the sealing surface can be made of hard alloy welding or lined with EPDM, which can withstand corrosive media such as sulfur-containing oil and gas, acid and alkali.
02
The internal rocker pin design eliminates external leakage points and enhances safety in hazardous medium scenarios.

Wide adaptability to various working conditions

Wide adaptability to various working conditions
01
Applicable media include water, steam, oil, corrosive liquids, etc. The working temperature ranges from -196 ℃ to 800 ℃, and the pressure rating can reach up to Class 2500 (42MPa).
02
Supports horizontal, vertical, or inclined pipeline installation without adjusting the valve body direction, suitable for complex working conditions.

Low flow resistance and fast response

Low flow resistance and fast response
01
The straight through flow channel design reduces turbulence and reduces fluid resistance by 20% -30% compared to traditional valves, making it suitable for high flow steam and oil transportation.
02
The valve disc can quickly close within 0.5 seconds through gravity or spring assistance, effectively suppressing water hammer effects and protecting pipelines and equipment.

Standardized design and high reliability

Standardized design and high reliability
01
Compliant with American standards such as ANSI and API, it adopts a compact structural design, with small volume, light weight, and easy installation and maintenance.
02
The valve disc is connected to the shaft through a rocker arm, which can provide 360 ° micro compensation, ensuring a tight fit of the sealing surface and a leakage level of ANSI VI, preventing medium backflow.
