We are using plastic material for our valve seat insert and want to confirm that the material is good for the pressure-temperature rating of the valve. Could i get advice on the stress mode to consider for this purpose -
1. Stress due to the seat being compressed to the ball due to pressure
2. Shear stress caused by friction between the seat and the ball while the ball is turning
3. Bending and/or shear stress as the pressure is trying to force past the seat insert
Direct advice will be appreciated as will reference to some design guide
