Valve selection consultation
Thread Content
Experts, please help me figure out which valve would be suitable for my situation Valve requirements: 1. The valve must not fail to close due to its own issues; it is necessary to ensure a stable gas supply for subsequent processes ； 2. When the gas supply volume for the production process is insufficient, this valve should be shut off via interlock to ensure a stable gas supply elsewhere?
Personally, I think choosing a cylinder-type FO shut-off butterfly valve would be sufficient, but it seems that both requirements cannot be met – only the first one can be satisfied. Everyone, please help and offer some suggestions
For the process gas supply volume, pressure detection points can be set to interlock this valve
