✧ Description

A ductile iron dual plate check valve is a type of industrial valve that is designed to prevent backflow in a pipeline or process system. This type of valve is constructed using ductile iron, a material known for its strength and durability. The dual plate design refers to the configuration of the valve, which consists of two hinged plates or discs that open in response to forward flow and close to prevent backflow.These valves are commonly used in various industries, including water treatment, wastewater management, irrigation, and industrial processes. They are often installed in pipelines to ensure the unidirectional flow of fluid or gas while preventing any reverse flow that could lead to system damage or inefficiency.Ductile iron is chosen as the material for these valves due to its excellent mechanical and corrosion-resistant properties, making it suitable for demanding applications. The dual plate design offers a compact and efficient solution for preventing backflow, and the hinged plates allow for quick response to flow changes, minimizing pressure losses.Ductile iron dual plate check valves are available in various sizes, pressure ratings, and end connections to accommodate different application requirements. They are typically designed and manufactured in compliance with industry standards such as API, AWWA, and ISO to ensure their performance, reliability, and safety.If you need more detailed information about ductile iron dual plate check valves, such as specific product specifications, installation guidelines, or compatibility with your application, please let me know so I can further assist you.

✧ Features of Ductile Iron Dual Plate Check Valve Wafer type

1. the structure length is short, its structure length is only 1/4 to 1/8 of the traditional flange check valve
2. small size, light weight, its weight is only 1/4 to 1/20 of the traditional micro slow closure check valve
3. the disc of the clamp check valve closes quickly, and the water hammer pressure is small
4. check valve horizontal or vertical pipe can be used, easy to install
5. the clamp check valve flow path is smooth, the fluid resistance is small
6. sensitive action, good sealing performance
7. the disc stroke is short, the clamping check valve closing impact is small
8. the overall structure, simple and compact, beautiful shape
9. long service life, high reliability

✧ Advantages of Ductile Iron Dual Plate Check Valve Wafer type

During the opening and closing process of the forged steel globe valve, because the friction between the disc and the sealing surface of the valve body is smaller than that of the gate valve, it is wear-resistant.
The opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for the adjustment of the flow rate. Therefore, this type of valve is very suitable for cut-off or regulation and throttling.
