THREE-WAY CONTROL VALVE WITH THREADED CONNECTION TYPE ZGM
The ZGM valves are udes as regulating and cutting off elements of the flow in the central heating, conditioning and ventilation sysytems. This type of valve can be designed for cold or hot water, steam, water with antifreeze and other liquids up to 150°C and for incombustible gases up to 80°C.
noiseless operation; resistance to cavitation, low aerodynamic noise,
possibility of work at high pressure drop,
possibility of using minature drivers,
small overall dimensions,
easy mounting and dismantling of valve and acutator,
wide range of choice of flow coefficients,
uniwersal mounting in instalation; large diversity of connectors: with ends for welding, with threaded ends and with flanges,
