Are there hydraulic safety valves made of steel with a PTFE lining? Are there hydraulic safety valves made of steel with a PTFE lining?
Hydraulic systems typically involve safety valve assemblies and other components that operate under high oil pressure; such valves usually have a small, precise flow area for regulation. The high-pressure deformation and hardness of tetrafluorine materials make them unsuitable for use in components for high-pressure processes. I’m not sure why such a request was made; please clarify. For reference.
I don’t know what the specific temperature and pressure are
For corrosive media, nitrogen-sealed storage tanks (at room temperature, 2 KPa) use a combination of a nitrogen seal valve + breather valve + hydraulic safety valve
