EVNB601AL-F40A Applications
The SMC EVNB601ALF40A is used on large-bore water, oil, air and vacuum lines in process plant, cooling towers, coolant circuits, tank filling and washdown systems. It is suited for high-volume hot water circuits up to 99 C, bulk coolant on-off control, and vacuum line isolation where a o40 mm orifice and Cv 28 are needed. The aluminium body keeps the assembly light at 1-1/2 inch line size, and air-operated actuation means no coil heat and free choice of remote pilot solenoid valve and voltage.
