They may be used also for intercepting liquids when hermetic seal, small pressure losses and compact construction in the flow direction are required. The peculiar features of these valves are the following: hermetic internal seal with sht valve small pressure losses possibility of rotating the butterfly of 360 î with consequent self-cleaning of the seat without removing the body from the piping not fixed assembly on the piping, since the two flow directions are possible butterfly with two sealing rings. This construction with hole in the body allows to check the internal seal of the valve vithout removing the valve itself from the piping. Moreover, the hole may be used also for lubrificating the body seal seat without removing the pressure from the piping chromium-plated body spheric seat for ensuring: * a longer life with hermetic internal seal * low control torques high reliability construdtion according to UNI 9245 standard face-to-face according to UNI 9245 and ISO 5752, MSS - SP 67, BS standard.
