DELO is offering a pneumatic micro-dispensing valve designed for media that is difficult to dispense. The DELO-DOT PN3 valve features increased jet performance, allowing adhesives to be dispensed in smaller quantities.
The minimum dispensing amount is reduced on average by a factor three over DELO’s previous pneumatic valve – DELO-DOT PN2. This valve has a maximum dispensing volume of nearly 14 mg, allowing it to work with a wide range of applications.
The DELO-DOT PN3 features an optimized fluid system geometry along with two different piston types, one for dispensing miniscule amounts, and one for small to medium drop sizes. Both configurations provide an operating frequency of up to 330 drops per second, a 10 percent increase.
The jet valve is simple to handle and is easily integrated into production lines with high output rates. A rotary wheel is used to set the stroke of the piston by selecting one of five different locking positions, ensuring high reproducibility, without the use of any additional tools. LED lights illuminate the respective position making it easier to check the stroke.
