Is it necessary to install a safety valve in a high-pressure hydraulic oil system?
Thread Content
The question is as stated: Is it necessary to install a safety valve in a high-pressure hydraulic system, or is it sufficient to use only a high-pressure interlock? If a safety valve is to be installed, is there any relevant basis for this? Thank you
It is usually required, but it’s not absolute; it depends on the needs of the process. Typically, a pressure relief valve is installed, with a safety valve connected in parallel to the return oil line.
If it is a centrifugal pump, it may not need to be installed

Install a check valve, also known as a pressure relief valve； When the pressure exceeds the set parameter, the check valve opens automatically to relieve pressure; otherwise it remains closed. The hydraulic system is designed in this way as a driving mechanism ； As a supplementary note, in accordance with safety design principles, safety valves are necessary.
