Wafer Type 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. Our Wafer Type Swing Check Valve has short face to face dimensions and low weight allows a simple space saving installation between the companion flanges. This design is lighter, and hence much cheaper when compared to swing and forged valves in the same diameter and pressure class.
