A balance seal for a valve, said seal comprising an annular seal element retained within a valve housing. The seal element has a seal well which links with the pressure on one side of the valve to urge a flexible seal leg with a foot into engagement with a moveable valve plug. The seal leg is prevented by an annular retainer from over-deflection.
