American Standard Check Valve

Industries

• Oil & Gas Industry: Used to prevent backflow in pipelines carrying crude oil, natural gas, and other hydrocarbons.
• Water Treatment Plants: Ideal for potable and wastewater treatment systems to ensure unidirectional flow.
• Chemical Industry: Suitable for handling aggressive chemical fluids that require corrosion-resistant materials.
• Power Generation: Applied in steam and condensate systems to prevent reverse flow that could damage equipment.
• HVAC Systems: Commonly used in heating, ventilation, and air conditioning systems to ensure proper fluid direction.

Specific Applications

• Pump Protection: Prevents backflow from damaging pumps in water supply and chemical injection systems.
• Steam Lines: Ensures unidirectional flow of steam in high-temperature systems, protecting equipment from water hammer.
• Chemical Injection Systems: Prevents reverse flow of chemicals, ensuring process reliability and safety.
• Fire Suppression Systems: Used in fire sprinkler systems to prevent backflow and maintain system integrity.

Installation Instructions

• Verify the valve size, pressure rating, and material compatibility with the pipeline and medium before installation.
• Ensure the flow direction matches the arrow indicated on the valve body to prevent improper operation.
• Install the valve in a horizontal or vertical position based on the type of check valve being used (e.g., swing check valves are typically installed horizontally).
• Use appropriate sealing materials (e.g., PTFE tape or gaskets) to ensure a leak-proof connection.
• Test the valve for proper operation after installation, ensuring that the disc moves freely and there are no signs of leakage.
