Hi,
can anybody tell me what could be the friction co-efficient value of steel with PEEK and steel with Glass filled PTFE ?

This reference would say it's a function of temperature: http://doc.utwente.nl/57546/1/Mens91friction.pdf

We are using these materials in Ball Valve.
In Ball Valve, hydro-static seat test is done with water and low pressure leak test is done with air.
