Ball valve structure There are many types of structures for ball valves, but they are basically the same. They are all round ball cores with opening and closing parts, mainly composed of valve seats, balls, sealing rings, valve stems, and other driving devices. The valve can be opened and closed by rotating the valve stem 90 degrees. They are used in pipelines to shut off, distribute, regulate flo...

Metal valves can be said to be key components and structures that are prone to corrosion and failure in engineering equipment. Generally, the sealing surface, valve stem, diaphragm, small spring, and other valve components of metal valves are made of materials, while the valve body, valve cover, and other materials are suitable for two or three materials. For valves used in high-pressure, highly t...

1. Introduction to Y-type Filter Y-type filters are an indispensable filtering device in pipeline systems that transport media. Y-type filters are usually installed at the inlet of pressure reducing valves, relief valves, constant water level valves, or other equipment to remove impurities from the media and protect the normal use of valves and equipment. The Y-type filter has the characteristics ...
