	The application and modes of operation of the particular valve you are looking at will dictate whether a retainer is required, and that will be answered by the valve designer. For instance, if you need to have full pressure shutoff from either flow direction of the valve, the retainer will probably prevent the pressure from blowing out the seat, assuming the shutoff design is for one direction flow. So you need to select a valve, then see if it will meet all of your operating conditions, including maintenance, cleaning and plant shutdown.

	PTFE is fine for any application where you can utilize wafer type valve. Go for it. __________________ If it ain't broke, don't fix it. Just build a better one.
