description | PROBLEM TO BE SOLVED: To protect a pneumatic valve from a water hammer flow in a pipeline, and to facilitate cleaning, repair and replacement of parts to remove foreign matters, etc., against the invasion of the foreign matters into a float valve element. SOLUTION: The pneumatic valve stores the float valve element guide 6 in a valve box 2 forming a through hole 3 in a bottom to guide a float valve element 4 and a floating valve element 5 by furnishing in a vertically overlapped shape. A doughnut shaped shock absorber 7 is floatably furnished between the outer bottom wall of the float valve element guide and the inner bottom wall of the valve box. When the water hammer flow comes from inside the pipeline, the shock absorber is pressed against the outer bottom wall of the float valve element guide, and brought into close contact with the outer bottom wall of the float valve element guide to prevent the excessive water by the water hammer flow from invading.
