ABSTRACT:
A regulation insert, for insertion in a valve housing in a liquid-carrying medium, having adjustable pre-setting for regulation and/or adjustment of liquid amounts in plants with liquid-carrying media for limiting the medium to a pre-set maximum amount, independently of a difference in pressure working across the valve, the insert having a tubular element which in a housing (3) can be displaced in the longitudinal direction of the regulation insert and lies up against a spring element (8), so that by displacement of the tubular element (2) a number of openings (9) in the housing (3) are opened or closed, and where the pre-setting for the regulation insert has several rows of openings (4, 5, 28), where at least one row of openings (4, 5) is disposed substantially along the circumference of the tubular element (2), and where the rows of openings (4, 5, 28), independently of one another, can wholly or partly block the throughflow in such a manner that a multiple of adjustment possibilities is achieved.
