• Water Hammer!-The Enemy of  Flow Pipeline

The water hammer occurs by sudden flow stopping caused by pump-off or pressure wave caused from the pipes bending.

• Smolensky check valve----No Impact , No Dining.

This commodity is the superb check valve designed to prevent the water impact with the operation of buffer hill&spring inside, thereby the water hammer&breakage of the pipes can be protected.

• Theory of Operation

When the pump starts, the pressure of the fluid pushes disc(2)then the fluid flows to chamber (c) through the chamber (A) &(B). When the pump stops, momentarily the pressure in the pipeline falls down then the short stagnation of the flow occurs and the reverse flow follows soonest. But at the same time by the action of spring(1)&buffer hill (4)disc(2) adheres to body seat(3)therefore any reverse flow&water hammer can be prevented.
