Microventil SMLD 300 - Vane mici și rapide de 4kHz, pentru dozarea precisă a gazului și lichidului în intervalul nl
SMLD 300, THE SMALLEST
With a minimum grid width of just 4.5 mm (with a special coil package even only 4 mm), the micro valves SMLD 300 are suitable for the tightest of spaces. Low-viscosity media can be dispensed with small flow rates. This type of valve offers a small internal volume of only 25 µl.
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. The micro valve can be exchanged quickly and without dismantling the entire valve holder and without disconnecting the electric connections.
