Abstract
A flow control valve (1) and a method for assembling a flow control valve (1) are disclosed. The flow control valve (1) comprises a first housing part (2) and a second housing part (3) attached directly to each other, in such a manner that the first housing part (2) and the second housing part (3) form a substantially closed housing. The first housing part (2) defines a first flow section (4), a second flow section (5), a connecting port (6) fluidly interconnecting the first flow section (4) and the second flow section (5), and a valve seat (7) arranged at the connecting port (6). The flow control valve (1) further comprises a frame part (9) arranged in an interior part of the housing formed by the first housing part (2) and the second housing part (3), the frame part (9) having mounted thereon a valve element (10, 13) arranged movably relative to the valve seat (7), a moving mechanism, e.g. including a spindle (12), for moving the valve element (10, 13), and an actuating mechanism, e.g. a stepper motor (14), for operating the moving mechanism. The frame part (9) is attached directly to the first housing part (2) or to the second housing part (3). The frame part (9) along with the …
