23C Pneumatic Glue Dispensing Valve | Precision Thimble Type

23C Pneumatic Glue Dispensing Valve – Precision Thimble Type

Achieve ultra-precise, repeatable adhesive deposits with the 23C Pneumatic Glue Dispensing Valve. Engineered as a double-acting, thimble-type dispenser, this stainless steel valve delivers consistently accurate single-liquid dispensing down to just 0.01ml per shot — making it the go-to choice for UV adhesives, silicone, and other low-to-medium viscosity fluids in electronics assembly, optical bonding, PCB manufacturing, and precision craft production.

Key Features

• Precision Thimble-Type Mechanism: Double-acting pneumatic action ensures clean cut-off with minimal stringing or dripping, even at high cycle speeds.
• Minimum Dispense Volume of 0.01ml: Ideal for micro-dispensing applications requiring tight volume control and dot consistency.
• Stainless Steel Construction: Durable, corrosion-resistant body withstands continuous use with UV adhesives, silicone, cyanoacrylates, and similar single-component fluids.
• Single-Liquid Design: Optimized for one-part adhesives and fluids — no mixing chamber required, simplifying setup and maintenance.
• Universal Compatibility: Integrates smoothly with standard benchtop dispensing controllers and pneumatic systems for semi-automated or automated production lines.
• Easy Maintenance: Tool-accessible thimble assembly allows for quick cleaning and needle/tip changes to minimize downtime.

Frequently Asked Questions

Q: What types of adhesives are compatible with the 23C pneumatic dispensing valve?

A: The 23C pneumatic glue dispensing valve is designed for single-component fluids including UV adhesives, silicone, cyanoacrylates, and other low-to-medium viscosity liquids. It is not intended for two-part mixing applications.

Q: What air pressure is required to operate this dispensing valve?

A: The 23C is a standard double-acting pneumatic valve compatible with typical shop air or regulated compressed air supplies. Consult your dispensing controller's specifications for the recommended operating pressure range, usually between 0.2–0.6 MPa for most dispensing systems.

Q: Can this valve be used with an automated dispensing controller?

A: Yes. The 23C dispensing valve is designed to integrate with standard benchtop or inline pneumatic dispensing controllers, making it suitable for both semi-automated workbench setups and fully automated production line applications.

Q: How is the thimble-type mechanism different from a diaphragm or needle valve?

A: A thimble-type (piston-thimble) valve uses a precision-machined thimble seat for a clean, positive seal and cut-off, which minimizes fluid stringing and delivers highly repeatable micro-dot deposits — especially valuable for UV adhesive and silicone dispensing in electronics manufacturing.
