Slow closing check valve series products can be used in water, sewage, sea water and other medium of the drainage pipeline, both to prevent the media back fork can effectively limit the destructive water hammer to ensure the safety of the use of pipelines. The structure has the characteristics of novel structure, small volume, light weight, small fluid resistance, reliable sealing, smooth opening and closing, abrasion resistance, long service life, slow closing and no medium influence, and has good energy saving effect. Micro slow close silencing check valve in the design fully consider the use of environmental requirements, the inclined plate structure, no vibration, no noise, to ensure smooth operation, hotels, residential environment is quiet, and has the effect of energy saving. DHH44X/H-10/16 type micro slow close check valve with delayed closing the local water system to flow down, thereby greatly reducing the hydraulic pressure impulse pump stop backflow, eliminate the destructive water hammer peak produced by the nitrile rubber sealing closure, good sealing performance, damping abrasion resistance, long service life and easy maintenance etc..
Micro resistance slow closing noise elimination check valve is suitable for clean medium, it is not suitable for the medium containing solid particles and large viscosity.
