Abstract

This invention relates to a valve with a valve housing which has several valve components. Sealing surfaces are provided on the circumference of the valve housing which correspond with a valve accommodating body carrying the valve housing. These surfaces are adapted to engage the valve accommodating body where (in dependence on the relative motion of the valve housing in respect of the valve accommodating body) the material volume existing on the circumference of the and plastically displace it into a circumferential recess of the valve housing.
