Piezoelectric jet valve AV-8500
Piezoelectric jet valve AV-8500

AV-8500 is a dual piezoelectric jet valve. The opening and closing of the needle are controlled by piezoelectric ceramics, which has a faster response speed and higher control accuracy. Compared with a single piezoelectric valve, its actual upper limit frequency will be higher, and the jet force will be greater, which has the advantage of dispensing high-viscosity glue. The initial position of the needle can be adjusted by the differential head to compensate for changes in the stroke caused by wear.It is suitable for epoxy, UV, silicone, acrylic, conductive silver glue, tuffy glue ,etc.
