		MA/MN/MNT series Conveyed flow on-off valves - “MA”/“MN” series - have been designed for cutoff requirements in fluids with very low flow rates. The valve seat diameter of the “MN” models equals 6 mm, while the one of the “MA” models equals 5 or 7.5 mm. The two models are very small if one considers the pneumatic control. Both valves are particularly suitable for laboratory and mixing plants, while the “MN”-type valve or the ENER version of the “MA” valve are ideal for steam. Technical features - “MA” model: • Body and intermediate in AISI 316. • Aluminium or AISI 304 steel servo control. • Plug gasket in PTFE. • Standard stuffing box in VITON, or in PTFE as optional. • Threaded gas connections 1/4” or 3/8”. • Maximum temperature from 150 to 160°C depending on the model. • Normally closed and double acting operation. Technical features - “MN”/“MNT” model: • Body and intermediate in AISI 316. • Servocontrol in AISI 304 with bronze ring nut with antiscuff treatment. • Plug gasket in PTFE. • Stuffing box in PTFE. • Threaded gas connections 1/4”. • Temperatures up to 170°C. • Normally closed, open, or double-acting operating mode.
