Can anyone tell me what the Maximum recommended pressures & temperatures are for continuous use for the following valve (ball or butterfly) seat materials?

Nylon, PTFE, RPTFE, Devlon & PEEK

Are there any pressure / temperature tables available?
I know there are chemical compatability issues as well but, I have found charts for them whereas nothing on the press. temp issue.
