Product Summary

Soft seat swing check valves should be mounted in the horizontal position, but may also be mounted in the vertical position, provided the disc is prevented from reaching the stalling position. In the latter case, however, the closing moment of the disc, due to its weight, is very small in the fully open position, so the valve will tend to close late.

To overcome slow response to retarding flow, the disc may be provided with a lever-mounted weight or spring loaded. One embodiment is of the power assist type constructed with convenient means for local daily testing the free swing portion of the check valve while another embodiment includes a manual test device. The valves may include friction free disc position indicators.
