Duplex Gate Valve

African Valve is the top Duplex Gate Valve Supplier in Egypt. Duplex gate valves are versatile, robust, and reliable valves that offer effective flow control and sealing in demanding industrial applications. Their advantages make them suitable for critical operations where safety, efficiency, and longevity are essential. These valves are constructed using duplex stainless steel. Duplex stainless steel is a corrosion-resistant alloy that combines the desirable properties of austenitic and ferritic stainless steels.

These properties make them suitable for a wide range of applications, especially those involving corrosive environments or high-pressure conditions. These valves are designed with two parallel gate discs that operate independently which provides a more reliable and effective sealing mechanism compared to a single gate valve. These valves are commonly used in applications where a high level of reliability, durability, and safety is required

Duplex gate valve involves sliding the gates between the seats to control the flow of fluid. When the gates are fully raised, the valve is in the fully open position, allowing maximum flow. The duplex design provides redundancy, as if one gate or seat is damaged or compromised, the other can still provide a seal and ensure the valve’s functionality.
