Stainless steel butterfly slow closing Check Valve Product Overview:

Stainless steel butterfly slow closing check valve is mainly composed of valve body, butterfly plate, heavy hammer, buffer device and other parts, installed at the outlet of the pump, by the medium pressure to push the butterfly plate open, normal or abnormal stop pump, by the butterfly plate weight and medium backflow pressure to push the butterfly plate, first quickly close most of the trip, and then use the damping effect of the buffer device, slow closing the remaining part of the trip, Valves that prevent the occurrence of destructive water hammer and participate in controlling the reverse speed of the pump. The valve butterfly plate assembly is divided into fast and slow two steps to close, to achieve both anti-countercurrent and weaken the role of water hammer, its slow closing device is installed outside the valve body, with non-pipeline medium as damping medium, stop the pump, the first speed closed 75%~90% stroke, after slow closing 25%~10% stroke, slow closing time within 120s can be adjusted.

Stainless steel butterfly slow closing check valve product advantages:

Stainless steel butterfly slow closing check valve products with novel structure, small volume, light weight, small fluid resistance, stable operation, reliable seal, wear resistance, good buffering performance and other characteristics, mainly used for industrial water supply, sewage treatment plant pump outlet, prevent the medium in the pipeline network, automatic elimination of destructive water hammer, so as to ensure that the pump and pipeline are not damaged.

Application:

The stainless steel butterfly type slow-closing check valve product features a novel structure, small size, light weight, low fluid resistance, smooth operation, reliable sealing, good wear resistance, and excellent buffering performance. It is mainly used in industrial water supply and wastewater treatment plants, at the pump outlet of the water pumps, to prevent the reverse flow of medium in the pipeline network, automatically eliminate destructive water hammer, thereby ensuring that the pumps and pipelines are not damaged.
