High-speed AC-741GM Diaphragm Micro Impingement Needle Valve

AC-741GM: This design is ideal for micro-precision dispensing, the firing pin impact needle bore plane off the glue, with a small aperture needle does not drip.

Suitable for: catalyst, marking ink number, silicone oil, UV glue, solvents, adhesives

1. The flow rate is adjustable, easy to calibrate and adjust, short adjustment time;

2. Small traveling cavity in the glue valve, clean glue break;

3. Easy disassembly, less maintenance;

4. Cylinder body, firing pin and nozzle, fluid bad, atomizing cap, piston are made of 303 stainless steel, long service life, wear and tear; 

Apply to: catalysts, ink marking, silicone oil, UV glue, solvents, adhesives
