Check valve manufacturers in Italy
Valvesonly Europe a well-known Check valve manufacturers in Italy, provides excellent valves that are especially made for optimal fluid management and efficiency. Dual plate check valves are backflow prevention check valves applied across a number of industries, such as chemical processing, power generation, oil and gas, and water treatment, for preventing backflow in piping systems and ensuring smooth and efficient operation.
Since these valves are small, light, and specifically designed for low-pressure drop applications, they are an improvement over standard swing check valve. Their rapid closure of their double-disc design protects against water hammer damage and backflow.
How Does a Dual Plate Check Valve Work?
A double plate check valve works by permitting the flow of fluid in one direction but not reverse flow. It is made up of two semi-circular discs that rotate around a central hinge.
As the flow begins, the pressure of the fluid opens the plates for free passage.
As the flow slows down, the plates start closing because of the spring-loaded mechanism.
When the flow reverses or stops, the plates shut fully, avoiding backflow.
The closing mechanism by spring provides quicker response and reduces pressure surges and hence the likelihood of water hammer effect in pipelines.
Benefits of Dual Plate Check Valves:
Compact & Lightweight: Smaller and lighter than standard check valves, easier to install.
Minimal Pressure Drop: Smooth and unobstructed flow is permitted by the dual-disc design.
Fast Closing Action: Minimizes the risk of water hammer and system damage.
High Durability: For extended performance life in high-pressure service.
Flexible Applications: Compatible with liquids, gases, and steam systems.
Difference between Swing check valve and Dual plate check valve:
While swing check valves and dual plate check valves both limit backflow, their designs and methods of operation differ.
Swing Check Valve: A single hinged disc on a swing check valve opens when flow is forward and closes when it is not. It is bigger and heavier, and because it takes longer to close, there is a higher chance of water hammer.
Dual Plate Check Valve: Reduces pressure surges and water hammer dangers by using two light plates that quickly close with the help of a spring-loaded mechanism. In addition, it is smaller and more effective than a swing check valve.
In applications demanding effective backflow prevention with little pressure drop, a dual plate check valve is the best option.
Dual Plate Check Valve Installation:
A dual plate check valve should be installed correctly for best performance. Observe the following:
Install the valve in the right flow direction as shown by the direction arrow on the valve body.
Mount the valve horizontally or vertically (with the flow upwards) for efficient performance.
Install with proper alignment to avoid pipeline stress.
Do not install the valve close to bends or pumps to reduce turbulence.
Check and service the valve regularly to guarantee long-term performance.
Functions of Dual Plate Check Valve:
Prevents Backflow: Provides one-way fluid flow to safeguard equipment.
Reduces Water Hammer: The quick-closing spring-loaded plates reduce pressure surges.
Improves System Efficiency: Low-pressure drop and smooth flow.
Safeguards Pumps & Compressors: Avoids reverse flow damage to vital equipment.
