A valve for a suction system, which comprises a sedimentation chamber (3) for collection of particles contained with the liquid sucked into the valve and suction outlet (6) having suction openings (8) in a float house (9), which suction openings (8) cooperate with a membrane (22), which is attached to a float member (21) in the float house (9) so that the membrane seals against the suction openings (8) when liquid do not reach the float house (9) and so that the area of the suction openings (8) is successively uncovered when the membrane (22) moves with the float member (21) at rising liquid level in the float house (9). |
