Poppet design
Poppet design
(OP)
We are working on a 3-way and a 4-way poppet style valve for the packaging industry. We are having significant problems with the poppet/seat design. We can not seem to get the poppet design to seal consistantly. The seat is about .500 in diameter and needs to seal using a load of .3 lbs and .001" compression. The valve is small and space is limited. Can anyone help?





RE: Poppet design
are you using a soft seat or hard seat?
these are important questions.
I have found that the 60 degree seats are ok for soft seats but a 70 degree seat is better for hard seats.
how have you sized your springs?
as for size restrictions look into a wave type spring.
