HC22 American Standard Check Valve is a high-performance, one-way valve designed to allow fluid to flow in a single direction while effectively preventing backflow. Because it operates automatically without the need for manual control or external actuation, it remains a critical component for protecting equipment and maintaining system integrity.
Exceptional Hastelloy C22 Performance
One of the primary advantages of this valve is its construction from Hastelloy C22 (HC22) alloy. Consequently, it provides superior resistance to pitting, crevice corrosion, and stress corrosion cracking. Furthermore, this material is exceptionally effective in environments containing aggressive oxidizing and reducing agents. Therefore, the HC22 check valve is the ideal choice for high-precision chemical and pharmaceutical applications.
Reliable Backflow Prevention
Check valves are commonly utilized in pipelines to prevent reverse flow, which could otherwise damage pumps, compressors, or other sensitive components. In order to meet diverse project requirements, these valves are suitable for:
- Liquids and Steam: Managing high-pressure fluid transport.
- Corrosive Gases: Ensuring safety in hazardous environments.
- Complex Industrial Lines: Protecting upstream instrumentation.
Durability and System Efficiency
Key features of this series include simple operation and minimal maintenance requirements. Additionally, the HC22 alloy ensures a fast response to flow changes even in harsh conditions. Ultimately, the ability to maintain consistent unidirectional flow helps enhance system efficiency, reduce operational downtime, and ensure safe operation in pressurized systems.

The American Standard Check Valve produced by our company is designed and manufactured in full accordance with strict American industrial standards. Because of its advanced and beautiful structural design, it is a premier choice for high-pressure systems. Specifically, this valve operates by automatically opening and closing the valve disc, relying entirely on the flow of the medium itself to prevent backflow.
Automatic Backflow Prevention
The American standard check valve—also commonly known as a non-return valve or counterflow valve—functions as a critical automatic safety component. Its primary purpose is to prevent the backflow of the medium. Consequently, it is essential for preventing the reversal of pumps and drive motors, while also stopping the accidental discharge of container mediums.
High-Performance Construction
In order to meet rigorous industrial requirements, our check valves are built with premium materials that ensure a long service life. Furthermore, because the seal is engineered to be exceptionally reliable, it maintains system integrity even under fluctuating pressure conditions. Whether you are managing water, oil, or gas, this valve provides a consistent “one-way” path for your pipeline.
Industrial Applications
Because of their durability and automatic operation, these valves are widely used across multiple sectors. Specifically, they are highly effective in:
- Petroleum and Gas: Protecting upstream equipment from pressure surges.
- Power Generation: Preventing reverse flow in steam and cooling lines.
- Chemical Processing: Ensuring the safe movement of corrosive fluids.
- Water Treatment: Maintaining pressure and preventing contamination.
