702V-A MINI DIAPHRAGM VALVE – Acetal

Katalogové číslo: 7020680

Controlled, consistent coatings and bonding in a miniature design.

The 702V-A mini-diaphragm dispense valve is designed for drip-free coatings and consistent shot-to-shot bonding of UV-cure adhesives and other low-to-medium viscosity fluids, especially where valve mounting space is at a premium.
At 60% smaller and 70% lighter than other dispense valves, the 702V-A mounts easily and can be positioned close to the production parts. With its lightweight design, the valve is also easy to move, which means less maintenance and wear on semi-automated and automated machine robotic arms.
The dispense valve incorporates an inert polymer diaphragm that isolates the fluid from the valve actuating cylinder and provides very fine flow control for all low to medium viscosity fluids. The unique design provides quick valve ON/OFF and the ability to rapidly obtain maximum flow rates.
The acetal fluid head will expand potential applications for the 702V Series valves by making them compatible with more assembly fluids, including anaerobic adhesives, many cyanoacrylates, UV-cure adhesives, and other fluids that can react with metal.
