Microvalva SMLD 300G(R) - Valve mici și rapide de 4kHz, pentru dozarea precisă a gazului și lichidului în intervalul nl
SMLD 300G, THE FLEXIBLE ONE
With a minimum grid width of 6 mm, the SMLD 300G is very space-saving, while offering maximum flexibility. These micro valves are suitable for a wide range of viscosities and are available in many configurations. Valve holder with integrated heating can also be combined with it. The internal volume is 65 µl.
The R (Resistant) type offers crucial benefits in regards of corrosion and the handling of aggressive medias, compared to SMLD 300G, but remains fully compatible in size and function for all SMLD products and components.
VALVE COILS
The valve coils are removable and available in different versions. They are optimised for very fast actuation times and minimal size.
VALVE INSTALLATION
Fastening type cylindrical: Grid width with highest resolution, small size. Suitable to our adapter nozzles. The thread fastening is designed to allow an easy exchange of the micro valves. especially suited when the micro valves should be as easy to exchange as possible.
