A valve insert (1) for a fluid flow valve, the valve insert (1) comprising a valve housing (3) having a bottom (13), an open top and at least one outlet opening (9); and a differential pressure regulator configured to maintain a substantially constant fluid flow through the valve insert (1), the differential pressure regulator comprising a hollow valve element (2) having an open bottom and an open top, said fluid flow being between said top and bottom, the valve element (2) being movable within the valve housing (3) along a longitudinal axis, L, of the valve insert (1) between an open position, wherein the at least one outlet opening (9) is uncovered, and a closed position, wherein the valve element (2) at least partially covers the at least one outlet opening (9), and a spring device (6) with a spring rate, the spring device (6) extending substantially along the longitudinal axis, L, and being configured to bias the valve element (2) towards said open position, wherein the spring rate of the spring device(6) varies in discrete steps according to a compression distance of the spring device (6), such that the spring device (6) in a first compression inter- val is compressed with a first substantially constant spring rate and in a sub- sequent compression interval is compressed with a second substantially constant spring rate, said second spring rate being greater than said first spring rate.
The valve comprises a housing with an upstream inlet, a valve inlet for communicating with a downstream flow, and a valve outlet. A pressure maintaining arrangement comprises a diaphragm and a valve member movable along an axis of the valve, the valve member setting itself in a balance between the upstream pressure on the one hand and the downstream pressure as well as a spring force on the other hand. The valve member comprises a circumferentially extending skirt (9) facing the valve seat (12). The skirt (9) comprises an abutment surface (17) facing an opposing surface (17a). An inner corner formed between said abutment surface (17) and an inner surface (18) of the skirt (9) is chamfered or establishes a non-linear transition (19) between the abutment surface (17) and the inner surface (18), said chamfer or transition (19) extending less than a distance (A) of 0.1 mm from the inner surface (18) in a direction towards the abutment surface (17) and less than a distance (B) of 0.1 mm from the abutment surface (17) in a direction towards the inner surface (18).
A control valve comprises a valve housing (1) having an inlet side (17) and an outlet side (18). The control valve also has a pressure maintaining arrangement for maintaining a constant differential pressure between the inlet and outlet sides, as well as an amount control arrangement for setting the maximum flow through the valve. A pair of cylinder shells located in the flow path have cooperating recesses which provide an uncovered area forming an opening (25). One cylinder shell is rotatable relative to the other cylinder shell by a rotatable handle (13), whereby a larger or smaller opening (25) between the cooperating cylinder shells may be provided. Both cylinder shells are axially displaceable within a seat hole (8), resulting in an increase or a decrease of the opening (25).
The control valve according to the invention is for use in liquid-carrying systems. It comprises a valve housing (1) having an inlet side (17) and an outlet side (18), said valve housing being provided with a pressure maintaining arrangement for maintaining a constant differential pressure between the inlet and outlet sides, as well as an amount control arrangement for setting the maximum flow amount through the valve and adjustment of it. The control arrangement comprises two cylinder shell elements (2 and 3) cooperating in the flow path, both having material removed from otherwise overlapping areas, thereby generating an uncovered area (25) in the flow path of the control valve. The outer cylinder shell element (3) is stationarily rotatable relative to the valve housing, while the inner cylinder shell element (2) may be rotated by means of a rotatable handle (13), whereby a larger or smaller opening (25) between the cooperating cylinder shell elements (2 and 3) may be provided. Both cylinder shell elements (2 and 3), which cooperate with the seat hole (8) of the valve housing, may also be displaced (26) in the axial direction, resulting in an increase or a decrease of the generated opening (25). Thereby, the flow amount may be adjusted prior to the presetting, e.g. by means of an actuator.

A control valve for use in liquid-borne systems, such as for instance central or district heating systems or other systems where there is a need for presetting the flow of liquid to a constant level, which does not change even if unforeseen pressure changes occur in the system. The control valve comprises a valve housing (2) in which a differential pressure regulator (3) and a presetting device are disposed. The differential pressure regulator (3) maintains a constant differential pressure between the inlet side and the outlet side by means of a spring force. The presetting device is used for presetting the flowing amount of liquid and comprises a rotary grip (14), a spindle (9), an outer cylindrical valve element (6) and an inner valve element (7). The outer valve element (6) has a slit through which the liquid may flow. The inner valve element (7) is disposed in the cylindrical valve element (6) and has a lower skirt of curve shape (8). Further, the valve element (7) is connected with the rotary grip (14) by means of the spindle (9), so that the opening of the presetting may be changed by rotation of the rotary knob.
