This KPS2000 piezo jet valve system combines very high repetition rate and a compact lightweight controller to meet demanding micro-dispensing tasks. It is built for high throughput applications where tight droplet control and easy integration matter. Choose this system when you need fast, repeatable drops with viscous fluids and minimal installation weight.
High-volume production often needs very fast droplet cycles while keeping drop size consistent. Too often valves slow the line, cause uneven deposits, or require heavy controllers that complicate robot mounting.
When a valve or its controller is heavy or slow, timing shifts and mechanical stress affect droplet formation. High-frequency operation also exposes weaknesses in fluid path design and drive control, so some valves show variation in drop volume or miss shots at speed.
The KPS2000 system uses a fast piezo drive and a light controller to deliver steady droplets up to 1200 Hz while handling thick fluids. The fluid path and nozzle options reduce clogging and let you tune drop size precisely. Main benefits:

| Integration | Dimensions | 125.5 × 75 × 20 mm |
Conclusion: high-frequency, stable drops come from fast pulse control and a clear fluid path. A rapid piezo pulse causes a pressure wave that pushes a micro-droplet through the nozzle. Pulse timing and amplitude set droplet size while steady inlet pressure keeps the fluid meniscus stable. For thick fluids, choosing the right nozzle and slightly raising fluid temperature (if allowed) improves flow.
Conclusion: select based on frequency need, droplet size, and fluid properties. Steps:
Frequency: use KPS2000 when cycle rates approach 1200 Hz or you need higher throughput.
Droplet volume: match nozzle size and driver settings to your target nL range.
Fluid compatibility: provide a fluid spec sheet; pick wetted parts (316L, PTFE, ceramic) accordingly.
Viscosity handling: if viscosity is very high, plan inlet pressure, possible warm-up, and a sample test.
Mounting: use the lightweight controller for robot end mounting where weight is limited.
Integration: confirm electrical connector and control signals match your system or request our driver options.
Q1: Can the KPS2000 run continuously at 1200 Hz?
A1: It is designed for high-frequency use. Continuous operation at 1200 Hz should be validated with your fluid, nozzle, and cooling conditions. We recommend a sample run.
Q2: What viscosity can it handle in practice?
A2: The system supports fluids up to 500,000 cps in many cases. Actual performance depends on fluid composition and temperature; please request a sample test for confirmation.
Q3: What is the smallest consistent drop I can achieve?
A3: Typical stable drops start around 2 nL with proper nozzle and drive settings. Production tuning is required to reach lower volumes reliably.
Q4: Is the 430 g controller easy to mount on a robot arm?
A4: Yes. The controller is lightweight for simpler mounting and less added inertia. Share your robotic interface details for a fit check.
Q5: Do you provide setup and tuning support?
A5: Yes, our applications engineers can help with parameter tuning, on-site or remote support, and sample testing.
