<p>The tap with rotary plug is for an integrated control block, having a passage capable of connecting two others leading to the bore in which it works, also if necessary an additional drilling connecting one of these to a drain. The plug is fixed to a protruding spindle onto which a handle fits. The plug (2) is accommodated in a cage (10), its angular position in the latter being controlled by guides working with a mounting plate (20), which in turn has tops determining its angular position in relation to the bore. Radial holes in the cage align with the passages leading into the bore but are of larger diameter, and accommodate sealing rings (16, 17) bearing against the plug and the wall of the bore and mounted in arched grooved rings curved to match the radius of the cage.</p> |
