Corrosion-resistant type Jetting piezoelectric dispensing valve for Corrosive glue application
Piezo jet valves are ideal for dispensing corrosive adhesives in high-precision applications. With a non-contact jetting mechanism and chemically resistant wetted parts such as ceramic and PEEK, they handle aggressive fluids with excellent stability. Common use cases include optical module assembly, camera lens bonding, MEMS packaging, and automotive sensor sealing. Piezo valves deliver consistent micro-dosing without air pressure, preventing contamination and ensuring high reliability in corrosive environments.

FAQ
Q1: How can piezoelectric valves resist chemical erosion by corrosive glue?
A1: The selection of corrosion-resistant materials (such as Teflon seals, perfluorinated seals, and 304 stainless steel flow channels) is the key.
The flow channel and seal ring materials need to be matched according to the specific glue composition (such as acid/alkalinity, solvent type).
Q2: How to clean the residual glue in the valve after long-term use? Does it support quick maintenance?
A2: The valve body flow channel components can support ultrasonic and glue remover soaking cleaning.
The design of the flow channel supports quick disassembly function (modular structure), and spare flow channels can be prepared for quick replacement and maintenance.
Regular maintenance cycles are recommended (such as flushing the flow channel after 12 hours of continuous use).
Q3: Will corrosive glue affect the jetting accuracy and life of the piezoelectric valve?
A3: Corrosion may cause aging or deformation of the seal, which indirectly affects the accuracy (such as dripping, unstable flow). It is recommended to use corrosion-resistant seals and clean and replace them regularly, which will not affect the accuracy and life of the spray valve;
It is recommended to verify the performance attenuation curve after long-term use through experiments.
Q4: How to ensure stable dispensing of high-viscosity corrosive glue?
A4: The valve drive parameters (such as pulse parameters and frequency) need to be matched to optimize the glue shear force.
Optional heating function (such as heating the valve body to 40~60℃) can reduce viscosity, but the glue temperature resistance must meet the standard.
Q5: Are there any industry verification cases or compatibility test reports?
A5: The actual corrosion tolerance and glue dispensing stability of the jetting valve need to be verified and evaluated. It is recommended that customers provide actual glue for verification.
