Valves Only is one of the leading Dual plate check valve manufacturers in USA that provides reliable, high-class, cost-effective valves that suit global standards. 

Dual plate check valves form a very crucial part of the pipeline system in the sense that they provide unidirectional flow as well as the prevention of backflow.  The dual plate check valves find applications in diverse different types of industries and are globally renowned due to the durable, space-efficient, yet powerful design they present.  

Dual Plate Check Valve: What is it? 

A two-spring-loaded disc or plate non-return valve opening on forward flow and closing on backflow is referred to as a dual plate check valve, or also at times referred to as a double-door or twin-disc check valve.  The mechanism is a preferred option in new-generation piping systems because it provides lower pressure drop and improved flow control.

Why is it required? 

Two-plate check valves are required for: 

• Backflow Prevention: It avoids reverse flow, which can damage equipment. 
• Pump and System Protection: It avoids water hammer and pressure surge. 
• Energy Efficiency: It enhances energy savings by reducing pressure drop. 
• Compact Installations: A substitute for typical swing check valves that is space-saving.

Key Components of Dual Plate Check Valve: 

• Valve body: It is typically made of carbon steel, cast iron, or stainless steel. 
• Dual Plates (discs): Two semi-circular spring-loaded plates that control flow. 
• Spring: To prevent backflow, a torsion spring assures rapid closure. 
• Hinge and Stop Pins: Provide alignment and mechanical support. 
• Seat Ring: Ensures a close closure to prevent leaks. 

Dual Plate Check Valve: Working 

The two plates are opened by the pressure and allow the media to pass through, when fluid continues forward.  The torsion springs quickly seal the plates to prevent backflow when the flow reverses or ceases.  The rapid-acting system enhances pipeline safety through prevention of water hammer. 

Advantages of Dual Plate Check Valve: 

• Light and compact: Ideal for tight spaces. 
• Low Pressure Drop: Enhances efficiency of the flow. 
• Quick Reaction: Reverse surge is prevented by prompt closure. 
• Corrosion Resistant: Strong materials can withstand harsh conditions. 
• Easy Installation: Fits between flanges with minimal effort, easy to install. 

Functions of Dual Plate Check Valve: 

• Prevents pipelines from flowing backward. 
• Protects compressors, pumps, and other critical components. 
• Maintains operational efficiency and safety. 
• Ensures the uninterrupted operation of sensitive processes.

1)Oil and Gas – Ensure smooth flow in refineries and pipeline.
2)Water Treatment – Used in pumping and filtration system.
3)Power Plant – Essential for cooling and steam system.
4)Chemical Processing – Prevent contamination and give controlled flow.
