SEALMECH Wafer Design Plate Type Check Valve has short face-to-face dimensions and low weight allows a simple space saving installation between the companion flanges. The valves are suitable to mounting between weld neck or slip on type companion flanges of different standards.
They are specially developed for applications where a low-pressure loss is essential. Opening and closing of the valve will take place at an extremely low-pressure difference over the valve disc. The eccentric disc shaft combination with the disc seat guarantees a positive shut off returning media. Wafer check valves are becoming the preferred type of check valve for most applications, due to their compact design and relatively low cost.
