A pressure-controlled valve arrangement comprises a valve housing (1) in which a through-passage for accommodating a first (11) and a second (12) hose section made of flexible or elastic material is provided. The valve arrangement furthermore has a control element which can be inserted into the valve housing between the two hose sections and touches these hose sections, the control element being movable in the valve housing and being capable of transmitting forces between the two hose sections in accordance with pressure changes in the hoses. The valve housing is a block-shaped body in which the passage is in the form of a unitary through-slot (4), on the base (5) of which one hose section (11) rests. Overall, the control element is a plate-shaped member (9) which can be displaced in the slot (4) in the direction of the depth of the slot. An adjusting screw (3) pointing towards the control element and the base (5) of the slot can be screwed into the slot (4). One end (15) of the adjusting screw can touch the other hose section (12) in the slot (4). The valve arrangement is easy to produce and assemble and the pressure in one hose section can be used to control the pressure and rate of flow in the other hose section. <IMAGE>
