ASME API Standard WCB CF8 CF8M Swing Check Valve For Water Steam And Oil Use
Product introduction:
A check valve refers to a type of valve with a circular valve disc as the opening and closing component, which acts to block the backflow of the medium by its own weight and medium pressure. It belongs to the category of automatic valves, also known as check valves, one-way valves, reflux valves, or isolation valves.
The wafer type lift check valve is composed of a valve body, valve disc, spring, etc., and is installed horizontally or vertically in the pipeline system to prevent medium backflow. It has a short structure, small volume, and light weight; The valve disc closes quickly and the water hammer pressure is low; Smooth flow channels with low fluid resistance; Sensitive action, good sealing performance, multiple materials can meet the needs of different media and pressures
