SELECTOSPRAY®
Roll Cooling Syste mThe 26mm / 1” Mini EVA (Mini E lectric V alve A ctuation)
Unique Offset pins require no alignment
Features � Class leading flow capacity � Fail closed operation � Pulse rate up to 5Hz � Easily and completely removable from the front
of the header � Operates at 26 mm / 1” centres
optional) � Stainless steel construction � Can be fitted with nozzle blocks or the
Lechler Selectospray® nozzle range� Due to the compact valve dimensions
header section is small, making this valve for roughing foil and foil mills.
Function The Mini EVA is an electro-hydraulic
utilising the same design principles as the larger EVA valve.
The Mini EVA has a class leading flow rate for a 26mm envelope. This enables Lechler engineers to design low aspect roll cooling headers allowing the optimum positioning inside the mill window The compact design is used in Lechler nozzle plates to ensure inclination angles can be achieved,the best spray solution available.
Advantages � Self aligning and cable free � No compressed air required � Large orifices for a laminar flow and a stable
spray pattern, providing effective and precise roll cooling
� Easily and completely removable from the front of the header
� No requirement to remove the header from the mill window
� Up to 120°C Operating Temperature� Tested to over 10 Million Cycles
