Al-Bronze Dual Plate Check Valve, API 594, C95800, 16 IN, CL150, RF

Key Specifications / Features

The Aluminum Bronze Dual Plate Check Valve Plant offers a high-quality Wafer Check Valve designed to meet stringent industry standards. This valve is manufactured in compliance with API 594 and ASTM B148 C95800, ensuring durability and reliability. With a 16-inch diameter (DN400) and a pressure rating of Class 150 LB (PN20), it features RF flanged ends for secure and leak-free connections. The dual plate design provides efficient flow control and prevents backflow, making it ideal for various industrial applications.

We are a specialized manufacturer of wafer check valves. These valves feature a central vertical pin shaft. When the valve is open, the resultant force of the fluid acts on the center of the sealing face of the disc. Meanwhile, the point action of the counter spring support force is located at the center of the disc surface. This design ensures that the disc opens from its root first. Unlike conventional valves, this mechanism prevents wear on the sealing surface when the valve opens, thereby enhancing the durability of the valve seal. Wafer check valves are designed to automatically open and close based on the flow of the medium itself, and they are primarily used to prevent backflow of the medium.
