Prevention of chattering. Check valve of a new generation that reduce piping space and allow direct attachment to a pump.

Prevents water hammer

The combination of a light, compact plates with a small moment of inertia and an optimized spring quickly stops the flow when the pump is turned off, preventing water hammer.

Direct installation to a reducer

Preventing chattering caused by fluid turbulence enables installing a check valve behind a reducer and a curved pipe. Straight pipe at upstream side is not necessary. Durability improved by decreasing vibration and noise.
