Stainless steel micro resistance slow closing check valve

A check valve refers to a type of valve whose opening and closing components are circular valve discs that act by their own weight and medium pressure to block medium backflow. It belongs to the category of automatic valves, also known as check valves, one-way valves, return valves or isolation valves. The valve disc movement can be divided into lifting and rotating types. Lift check valves have a similar structure to globe valves, except for the lack of a valve stem that drives the valve disc. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). When the inlet pressure exceeds the sum of the weight of the valve disc and its flow resistance, the valve is opened. On the contrary, when the medium flows back, the valve closes.

This product is used on water supply and drainage pipelines, installed at the outlet of the water pump to prevent medium backflow and eliminate destructive water hammer, and can effectively reduce the pressure caused by water hammer when the valve is closed, ensuring the safe operation of the pipeline network. This product has the characteristics of light valve disc, large opening, low fluid resistance, innovative design of water hammer elimination mechanism, stable and reliable sealing performance, wear resistance, long service life, smooth operation, no vibration, no noise, etc.
