Frequently Asked Questions
1. What types of fluids is the AC-741GM suitable for?
The AC-741GM is designed to handle low to medium-viscosity fluids (ranging from 1 to 50,000 cP) including catalysts, marking inks, silicone oil, UV glue, solvents, adhesives, and greases.
2. How is the flow rate adjusted on this needle valve?
The flow rate can be adjusted within a range of 0.01 to 50 mL/min. The design allows for easy calibration and adjustment, significantly reducing setup times during production shifts.
3. What materials are used to construct the valve components?
The critical components, including the cylinder body, firing pin, nozzle, fluid path, atomizing cap, and piston, are made of durable 303 stainless steel. The sealing system utilizes chemical-resistant PTFE to prevent internal leakage.
4. Can this valve be integrated into automated production systems?
Yes, it comes with a programmable digital controller featuring a touchscreen and PLC interface, making it highly compatible with automated and manual production line setups.
5. What makes the AC-741GM design leak-free and precise?
It features a small traveling cavity in the glue valve combined with a firing pin impact needle bore plane cutoff design. This mechanism prevents dripping even when using small-aperture needles, ensuring clean fluid breaks.
6. Is maintenance complex for the AC-741GM?
No, the valve is engineered for easy disassembly and cleaning. Due to its robust design and fewer wear parts compared to traditional needle valves, it requires minimal maintenance.
