Wafer Check Valve
Wafer Check Valve type combine a simple but robust construction with reliablity. 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 connection. in combination with the disc seat guarantees positive shut-off of the returning medium.
