Definition and difference between safety valve and relief valve
Safety relief valve, also known as safety overflow valve, is an automatic pressure relief device driven by medium pressure. It can be used as both a safety valve and a relief valve depending on the application. Taking Japan as an example, there are relatively few clear definitions of safety valve...Read more -
Gate valve maintenance procedures
1. Introduction to gate valves 1.1. Working principle and function of gate valves: Gate valves belong to the category of cut-off valves, usually installed on pipes with a diameter greater than 100mm, to cut off or connect the flow of media in the pipe. Because the valve disc is in the gate type, ...Read more -
