Dispensing valves are widely used in electronics, automotive, medical devices, aerospace and many other industries. This article explains the working principle of dispensing valves and introduces key factors for proper product selection.
Working Principle of Dispensing Valve
Pressure or pressure‑reduction drives adhesive into the valve core chamber. Adhesive flows out when the valve core opens and stops when it closes. The flow rate and output pressure can be adjusted by controlling the opening duration and trigger frequency of the valve core.
How to Choose the Right Dispensing Valve
Selecting a suitable dispensing valve is essential for stable production‑line operation. First evaluate workpiece characteristics including shape, material and size. Then analyze adhesive properties such as viscosity, fluidity and color. Pick the proper product based on these factors.
Four major aspects for reference:
- Model & Specification：Performance varies among different models. Confirm your production requirements and select specifications according to viscosity, dispensing volume, accuracy and other technical parameters to match real‑world dispensing demands.
- Valve Material：Adhesives differ in viscosity and fluidity. The valve material must be compatible with the applied adhesive medium.
- Special Functional Types：Options include pneumatic type, electric type and others. Choose proper model and specification to fit different production environments.
- Cost & Price：Take quality, power and working efficiency into full consideration. Compare product costs and prefer solutions with long service life and good cost‑performance.
