Dual Plate Check Valve
Dual Plate Check Valves are automatic mechanical valves, which open with a forward flow and shut to a reversal inflow. The key feature of the check valve is to secure the mechanical devices in the pipe system by avoiding the reversing of the fluid. The swing check valve is an economic kind of check valve, but it has a higher slamming effect.
Feature and Benefit of Dual Plate Check Valve.
The Dual-Plate Check Valve is a non-return valve that is comparatively stronger, lighter in weight, and compact in size than the conventional swing control valve or lift control valve.

• Pressure drop in a dual plate check is very low as compared to other check valves.
• Low wear and tear of the seat as it has a design of non-slamming type.
• Water hammers are almost negligible in dual-plate check valves because valve closure does not rely on backpressure and backflow. Each plate, which is half the size of a swing check disc, offers a straight flow path, providing the least resistance. As a result of spring-assisted closing, the valve closure begins as soon as the flow velocity decreases below the intended minimum velocity, and then the closing rate flows into the flow velocity reduction pattern. The valve shuts as the flow rate reaches zero and well before the flow is reversed. This reduces the water hammering.
• Non-Slam Design: The two plates in the Dual Plate Check Valve are mounted vertically in the middle for horizontal installations, completely removing the influence of gravity. Also, the momentum produced as they travel to a closed position is just a fraction of what is developed in a swing check valve. Further due to the spring-assisted closure, the valve shuts as the flow velocity reaches zero and until the flow reversal. When it begins to close, the flow, as such, cushions the plates and the seat, thereby reducing slamming.
• Dual Plate Check Valve Application
• A dual plate check valve is the most suitable type of check valve that can be used for almost any configuration of material and system parameters used in various applications, some of the typical applications are:

• Water systems like boilers, Potable water, Fire safety system, Cooling & Heating water system, etc.
• Petrochemicals: Offshore/Onshore applications, LPG, LNG, Lube oil, Cryogenics, etc.
• Hydrocarbon: In almost all the applications.
• Air & Gas applications like Chlorine, Hydrogen, Nitrogen, Carbon Dioxide, Oxygen, Etc.
• Metallurgical and Chemical Applications: Sugar, Pharmaceuticals, Paper, Cement, Steel, Aluminium, Copper, zinc, etc.
