The clamping arrangement has a foundation, stationary and mobile plates, a loading hydraulic cylinder on a rotary plate, a pillar and a buckle between the mobile and the stationary plates. On the stationary plate there are sliders interacting with the rods of the hydraulic cylinders of the clamp of the flanges of the valves. The pillar consists of mobile and motionless parts connected between themselves with joint power half-couplings. On the mobile and the motionless plates there are lugs in the shape of concentric circumferences whose diameters are equal to the diameters of the lugs on the flanges of the tested valves, and their number is defined by the nomenclature of the valves.
