The valve electromagnetic gas Madas EVAP/NC BUT Du 15 – solenoidal normally open valve of the Madas trademark (Italy). This reliable and durable device intended for operation in systems of remote control water-heating and boilers, household and technological heating installations, and also heatgenerators. The valve is used to automatic overlapping of streams of the nonaggressive environment, for example, of dry gases (natural gas, methane, air, the liquefied gas and so forth) . Besides, it can carry out the function both locking, and regulating. The valve Madas EVAP/NC BUT Du 15 belongs to devices with the on-off principle of cutting off of a stream of a working environment. Automatic cutting off of a stream happens by giving of tension on the coil, to be exact, on an electromagnet. When tension is absent the valve, is abroach. Therefore in so-called, normal, situation when tension does not move in system, the valve it is closed. The case of the electromagnetic gas valve Madas EVAP/NC BUT Du 15 is manufactured of aluminum, the range of working temperatures fluctuates from-30 to +60 °C. You can complete the valve of one of coils from 12V to 220V depending on necessary supply voltage., and also to choose necessary pressure for work: from 0,36 bars to 6 bars.
