8. TS9800 JET VALVE
8.1 Valve Modules
The TS9800 Series consists of three basic modules:
• Actuator System module (1)
• Fluid Manifold module (2)
• Nozzle Unit module (3)

The actuator system is the heart of the Jet Valve. It contains the
electronics for sensor and piezo actuator signals. It also contains the
mechanics for the tappet drive. The housing is encapsulated to avoid
contamination and intrusion of humidity.
Fluid Manifold can be easily removed from the actuator system by
loosening two screws. This allows a stand-alone cleaning process.
Nozzle Unit can be easily changed and cleaned to minimized down
times. The nozzle insert is a consumable item and it can be easily
replaced.

8.3 SPECIAL FEATURES
8.3.1 Normally Open
In the non-operative mode, without supply voltage, the valve is
opened. However, this is usually not a problem regarding the
fluid leakage. With the high viscosity fluid, the valve will leak
very slowly or not at all. In order to eliminate the fluid
leakage, the supply pressure to the material syringe must be
disconnected before shutting down the control unit.
8.3.2 Quick-Change Concept
The “Quick-Change” (which consists of nozzle adjustment
nut, nozzle bushing, O-ring seal and nozzle insert) allows a
very fast exchange of the nozzle unit. The electronically
controlled calibration process helps to adjust the nozzle unit
quickly and precisely to the tappet.

8.3.3 Modularity
All TS9800 Jet Valve System are built strictly modular. Spare
parts are simple and quick to replace so time and cost for repair
can be significantly reduced.
8.3.4 Easy handling
The valve can be controlled in all functions from the control
unit and it can be integrated into your existing setup.
8.4 Materials applied
Only high-quality materials are used to manufacture the TS9800
Jet Valve System.
• All fluid contacting parts consist of high-alloyed rust-proof
and acid-resistant stainless steels as well as the high-
performance polymer families of polyetheretherketone
(PEEK) and of polytetrafluorethylene (PTFE).
• The nozzle inserts can be adapted to your dispense media and
consist alternatively of two materials Tungsten Carbide or
Zirconia Ceramic.
