【Seat Tightness】:

1. When pressure is on the insert side,pressure is applied under the seat lip.This further amplifies the sealing force between the disc and the seat.

2. When pressure is on the non-insert side,the disc moves into the seat.Due to the spherical profile of the disc,the more the disc moves into the seat,the tighter the shut-off.Excess movement of the seat is limited by the flexible lip which contacts the bottom of the groove in the insert ring.
