Title: A METHOD FOR ASSEMBLING A VALVE AND A VALVE
Abstract:
Disclosed is a method for assembling a valve (1). The method comprises the steps of • assembling a stem assembly (2) by positioning collar means (8) on a valve stem (4) so that collar friction surfaces (5) of the collar means (8) meshes with stem friction surfaces (6) of the valve stem (4) to substantially prevent mutual axial displacement between the collar means (8) and the valve stem (4), • bending resilient locking means (7) of the collar means (8) inwards by forcing the stem assembly (2) into a stem hole (9) in a valve housing (3), wherein a diameter (DH) of the stem hole (9) is smaller than the outer diameter (DL) of the locking means (7), and • locking the axial position of the stem assembly (2) in the valve housing (3) by positioning the locking means (7) at a locking groove (10) in the stem hole (9) to allow the resilient locking means (7) to expand outwards into the locking groove (10). A valve (1) for control of a fluid flow is also disclosed.
