Check Valve Suppliers

Valves Only is your Trusted Check Valve Suppliers in USA. Valves are essential component in any industrial system that involve fluid regulation. Whether it is oil and gas, water treatment or power plants, choosing the right valve ensure efficiency and safety. We understand importance of high quality valve and provide some of the best option in industry. 

Check Valve 

It is type of valve that allow flow of fluid in one direction while preventing backflow. Unlike other valve that require manual operation check valve function automatically based on the movement of fluid. They are widely used in pipeline to maintain pressure, avoid contamination and protect equipment from potential damage caused by reverse flow.  

Key Part and Working Mechanism  

A check valve consist of following key part:  

• Body: The outer casing that house all internal component. 
• Disc: The movable part that controls the flow direction. 
• Seat: A sealing surface where the disc rests to prevent backflow. 
• Spring (optional): Some designs include a spring that assists in quick closure.  

The working principle is simple: when fluid flows in the correct direction, the disc lifts, allowing passage. When the flow stops or attempts to reverse, the disc closes, preventing backflow. This automatic action makes check valves highly effective in maintaining the integrity of the pipeline.  

Benefits of Check Valve: 

• Prevention of Backflow: Ensures fluids move in the intended direction, reducing contamination risks. 
• Low Maintenance: Their automatic operation eliminates the need for frequent monitoring. 
• Energy Efficiency: By maintaining consistent pressure check valve enhance overall system efficiency. 
• Extended Lifespan: Protect pump and other sensitive component from damage due to reverse flow.   

Non-Slam Swing Check Valve 

It is specially designed to eliminate slamming effect that occur in conventional check valve when flow stop abruptly. The sudden closure of standard check valve can create pressure surge, leading to water hammer damaging phenomenon in pipeline.  

How it works? 

It features disc that swing open when fluid flow forward and gradually return to its seat as flow slow down. The controlled closing action, often assisted by spring or damping mechanism, ensure smooth transition, preventing slamming and reducing noise.  

Differences Between a Check Valve and a Non-Slam Swing Check Valve  

• Closing Mechanism: Traditional check valve may close abruptly, while non slam variant ensure controlled closure.  
• Noise & Vibration: Non slam check valve reduce noise and vibration, making them ideal for sensitive application.  
• Longevity: Due to reduced stress on component, non slam valve tend to last longer.
