<p>In a directional seat valve all the valve seat components disposed axially adjacent each other in the housing bore are held between two closure screws and for assembling the valve the movable valve elements are supported via the valve actuating pin on a punch. By turning the closure screws the valve seat components can be adjusted in the axial direction so that the actuating pin has a predetermined spacing with respect to the housing end side of the valve. An advantage resides in that in the assembly of the valve itself a constant dimension can be set between the actuating pin and the housing and consequently an adjustment on subsequent attachment to the actuating means dispensed with, in particular an adjustment of the actuator cooperating with the actuating pin.</p> |
