2 Description Lockshields Series 9UM, 96UM, 9UM, 96UM, are used as shut-off and control devices for heat emitters (radiators, fan coil convectors, radiant panels, etc.) in heating and air-conditioning systems. The lockshields are available in the configuration with straight or angle body, with male or female thread and should be installed on the return pipe of the heat emitter. They are fitted with an O-RING sealed straight tailpiece. 9UM Micrometric lockshield with angle body for iron pipes Type Code Size Kvs Weight (g) 9UM 9UMSN /", 0 9UM 9UMSN /", 0 9UM 9UMSN /", UM Micrometric lockshield with straight body for iron pipes Type Code Size Kvs Weight (g) 96UM 96UMSN /", 96UM 96UMSN /", 0 96UM 96UMSN /", 0 9UM Micrometric lockshield with angle body for copper or polyethylene pipes Tipo Codice Size body Size Tube Kvs Weight (g) 9UM 9UMSNX /" /", 70 9UM 9UMSN /" /", 0 96UM Micrometric lockshield with straight body for copper or polyethylene pipes Tipo Codice Size body Size Tube Kvs Weight (g) 96UM 96UMSNX /" /", 96UM 96UMSN /" /", 0 pplication lthough the lockshields are not true setting devices, they can also be used for hydraulic balancing of the heat emitters by adjusting the plug stroke. Operation Operation is through the manual movement of the plug which shuts off the heat carrier fluid. For hydraulic flow rate and pressure drop characteristics, see relative charts.

3 djustment To adjust the lockshield, remove the cap and turn the plug with relative wrench (rticle ) or wide-bladed screwdriver. The setting positions are identified by the numbers of turns in opening the lockshield starting from the fully closed position (See table). Reliability of the lockshields series 9UM, 96UM, 9UM, 96UM, is ensured thanks to the 0% testing of the production which checks the hydraulic sealing properties of the valve body and its components towards the outside and that of the plug in its flow shut-off function. Installation Selection of the lockshieds depends on the size of the connection to the radiator and the connecting pipe. Lockshields Series 9UM, 96UM, 9UM, 96UM, can be installed on heat emitters supplied by iron, copper and plastic piping.
