SPOT 64 Precision Pneumatic Spray Dispensing Valve – Micro Atomizing Fluid Control
Engineered for exacting industrial applications, this SPOT 64 Precision Pneumatic Spray Dispensing Valve delivers ultra-precise micro-atomization of coatings, adhesives, inks, lubricants, and other industrial fluids. Built from durable aluminum alloy, this valve integrates seamlessly into automated dispensing systems and solenoid-controlled setups — giving engineers and technicians repeatable, drip-free fluid control at every cycle. Made in Mainland China.
Key Features
- Micro Atomizing Technology: Produces a fine, uniform spray pattern ideal for precision coating and adhesive dispensing across sensitive components.
- Aluminum Alloy Construction: Lightweight yet robust body resists corrosion and withstands demanding industrial environments.
- Solenoid Valve Compatible: Works with standard solenoid valve configurations — supports normally open (A) and normally closed (B) air channel selection for flexible integration.
- Drip-Free Sealing: Precision-engineered glue lock seal and glue lock head ensure clean start/stop dispensing with no unwanted dripping.
- Wide Fluid Compatibility: Handles coatings, adhesives, UV resins, inks, lubricants, solvents, and other low-to-medium viscosity industrial fluids.
- Broad Industry Applications: Suitable for electronics assembly, semiconductor packaging, PCB protection, LCD/LED bonding, automotive coating, hardware adhesion, solar panel manufacturing, and laboratory use.

How the Air Intake Works
Dispensing valves are controlled by solenoid valves, which feature one air intake and two air outlets. By selecting the direction, you can configure the valve for your application:
- Suction / Plunger / Diaphragm Type: Normally open (A) connects to the middle valve position; normally closed (B) connects to the last pipe fitting.
- Ejector Type: Normally open (A) connects to the last valve pipe; normally closed (B) connects to the middle position.
The solenoid valve directs airflow to control the up-and-down movement of the valve's cylinder piston for precise, repeatable dispensing cycles.
Troubleshooting Tips
Checking for seal integrity: When both the dispensing valve and feeder are properly ventilated and fluid flows into the valve, remove the needle and observe the valve outlet. If fluid flows without the needle engaged, the glue lock seal or glue lock head may need replacement.
Addressing post-stop dripping: During operation, remove the needle and purge the fluid — the output should be a continuous strip with no bubbles or breaks, and flow should stop cleanly. If dripping persists after stopping, either switch to a needle with a larger inner diameter, or reduce supply pressure to lower the fluid flow rate and minimize negative pressure in the needle.

Frequently Asked Questions
Q: What types of fluids is this pneumatic spray dispensing valve compatible with?
A: The SPOT 64 Precision Pneumatic Spray Dispensing Valve is compatible with a wide range of low-to-medium viscosity industrial fluids, including adhesives, UV resins, coatings, inks, lubricants, and solvents. It is widely used across electronics, semiconductor, automotive, and laboratory industries for precise fluid control.
Q: How does the solenoid valve control the dispensing valve?
A: The solenoid valve has one air intake and two air outlets (normally open A and normally closed B). By selecting the correct port configuration — which varies by valve type (suction, plunger, diaphragm, or ejector) — it directs compressed air to move the cylinder piston up and down, controlling when and how much fluid is dispensed.
Q: What should I do if my dispensing valve drips after stopping?
A: Post-stop dripping is usually caused by excessive supply pressure or a needle with too small an inner diameter creating negative pressure. To resolve this, try replacing the needle with one that has a larger inner diameter, or reduce the supply pressure to slow the fluid flow rate. Both measures help reduce negative pressure buildup at the needle tip.
Q: What is the body of this dispensing valve made from?
A: The valve body is constructed from aluminum alloy, providing a lightweight yet durable and corrosion-resistant build suitable for continuous industrial use.
