Shut-Off Valves Air vent valves with float Series MVD - MV - MKV - MKL - 2161C - MXV Are automatic and/or manual devices for discharging air from heating and air-conditioning systems. These devices are used in all traditional heating systems (independent, central, radiant panel, etc) for discharging air during the filling phase and the air released into the water during the heating phase, which obstructs the normal circulation of the heat carrier fluid above all at the points where it circulates at a low speed (heat emitters), thus reducing their thermal efficiency. The air vent valves allow the air to be discharged at the points of the system where it accumulates (distribution manifolds, tops of the risers or directly in the boiler). Air vent valves with float Series MVD - MV - MKV - MKL - 2161C - MXV

Preassembled fixed-point control distribution unit for radiant panel heating systems DOMORADIANT The preassembled unit of the DOMORADIANT Series is designed for modern radiant panel heating systems. It performs all the necessary functions for such purpose, namely: - providing tight-sealed hydraulic connection of the pipe ends in the various coils making up the radiant panels (CPRFL series); it allows shut-off (if required) and the necessary setting and monitoring of all flow rates - providing the hydraulic connection for the pipes feeding the towel-rail radiators (807MF series) - automatic air venting - mixing of the fluid for the radiant panels and holding it at low temperature - ensuring the supply and head of the high temperature circuits - visual temperature monitoring. The device designed for mixing and delivering hot water at the lower temperature consists of a 3-way mixing valve operated by a thermostatic actuator with remote sensor type FH-148SD (range 20-50 °C). The required flow rate for feeding the radiant panels is supplied by a 3-speed electrically driven pump. The manifold can supply up to 12 low temperature circuits and up to 3 radiators. Each return outlet is arranged to receive thermostatic actuator series 22C for adjusting the ambient temperature in each individual room. The supply outlet is fitted with flow meter FLMR series able to measure and adjust the flow rate accordingly. Optionally the various electrothermic actuators (when provided) can be controlled by a modular control box WFHT series, from 4 to 6 zones through room thermostats. The Master module is provided with a control relay for the electrically-driven pump which is automatically disactivated when all the actuators are closed. When the actuators are not controlled by the modular box, a by-pass kit is available for controlling the differential pressure. Such kit should be attached to the head connections of the manifolds. The system, which has been hydraulically tested in the factory, is housed in a special inspection box with single door and with epoxy finishing. DOMORADIANT

Remote thermal units for centralized combustion systems Series DOMOCAL The multi-function DOMOCAL thermal units are designed to control the heat supply, coming from a district heating station or produced by a conventional heating system, to the individual apartments, whether for space heating or preparation of Domestic Hot Water (DHW). DOMOCAL feeds the heating circuit of each apartment and allows independent control of the room comfort level thanks to the action of a timing thermostat installed in the ambient, that actuates the zone valve incorporated in the unit. Supply of the DHW produced by the heat exchanger is made available merely by turning the tap for hot water delivery. Temperature of the hot water is controlled by a thermostatic mixing valve which holds it at the level chosen by the user. The devices and pipes making up the unit are factory-assembled and are inserted in a metal support structure which allows pendant installation. All inlets and outlets are provided with shut-off valves and union fitting (three-piece): during installation, this allows preparing just the frame at first, then inserting the "body" of the unit at a later stage. Likewise it is easier for the heating system operator to carry out the required maintenance work and also full replacement of the unit when necessary. The DOMOCAL thermal unit is equipped with a direct heat (hot/chilled) metering system, approved by the PTB Institute of Berlin, which allows subsequent allocation of the costs based on consumption, thus encouraging a more rational use of energy with consequent energy instant savings. The thermal energy drawn from the primary network (user consumption) is measured with great accuracy by a meter whose data/consumption reading is concentrated, transmitted and processed. The system is also provided with a meter for the drawing off cold mains water. DOMOCAL series

Thermal safety drain and draught regulator Series STS - RT - Thermal safety drain Series STS : The heat sensitive element, immersed in the boiler water, expands as temperature increases thus causing the valve plug to open when the temperature reaches the set value. - Draught regulator Series RT: The draught regulator heat sensitive element, immersed in the boiler water within a sheath, acts on the combustion by appropriately varying introduction of the combustion-supporting air in the boiler in relation to the water temperature. Such regulation is by opening or closing the air inlet door in the boiler. Series STS - RT
