Product introduction

Using the pressure of the pipeline itself, the operation design is simple and reliable. When there is a water hammer at the downstream outlet, the main valve will be closed quickly to prevent damage to the upstream pipe network and equipment. When the water pump is started to supply water and the pipeline is in a state of no water and no pressure, the slow closing check valve will be opened slowly to supply water to the downstream to reduce the impact of high-speed water flow on the downstream pipeline and equipment.

Product function

When the inlet pressure is higher than the outlet pressure, the valve will automatically open later to avoid water hammer caused by rapid opening. When the rear pressure is higher than the front pressure, the rear high pressure enters the upper chamber of the main valve through diversion and closes the main valve. Automatically eliminate destructive water hammer, so as to ensure that the water pump and pipeline are not damaged.

Product application

It is used at the pump outlet of industrial water supply and drainage, sewage treatment plant and high-rise buildings to prevent the reverse flow of medium in the pipe network.
