702V-A MINI DIAPHRAGM VALVE – Acetal

Product code: 7020680

Controlled, consistent coatings and bonds in a miniature design

The 702V-A miniature diaphragm valve is designed for drip-free coatings and consistent bonding in spaces with limited access.

• 60% smaller and 70% lighter, reducing wear and tear on robotic arms.
• Inert polymer diaphragm isolates fluid from the actuator cylinder.
• Fast on/off cycling and very fine flow control for consistent results.
• Acetal head ensures compatibility with anaerobic adhesives and cyanoacrylates.
• Ideal for metal-reactive fluids and UV-cure adhesives. More
