Features:

The structure length is short, which brings great convenience to the valve installation, handling, storage and pipeline layout, and can save costs.
Reduce line vibration, in order to reduce line vibration to a minimum or eliminate line vibration, the check valve must be closed as soon as possible before the liquid flow has a chance to reverse flow. The size of each flap in a double-lobe check valve Only half the size of a fully constructed check disc, it experiences reduced fluid resistance and faster movement to the closed position. They have a radius of rotation half that of conventional check valves.
Its leading distance from the open to the closed position is halved, thus reducing travel time by up to 50%
The double-piece check valve reduces water hammer, and the flaps of the double-piece check valve have been greatly reduced in weight, which can reduce the slamming and water hammer phenomena to a small limit Degree.
