J. D. Check Valves type combines a simple but robust construction with reliability. They are specially designed and developed for applications where a low pressure loss is essential. J.D. Wafer Type Swing 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 plate type companion flanges of different standards. The short face to face dimensions and the low weight guarantee a simple and space saving installation between the bolts of the connecting flange.
The eccentric disc shaft connection in combination with the disc seat guarantees positive shut-off of the returning medium. Wafer check valves are becoming the preferred type of check valve for most applications, due to their compact design and relatively low cost.
