Product Data Sheet TS5440 Series Needle Valve The TS5440 Series Microshot Needle Valve is a normally closed needle and seat dispensing valve, which is designed to dispense low - medium viscosity fluids. With a zero dead volume seat design, the TS5440 Series can dispense very precise deposits over a wide range of deposit sizes, down to a fraction of a micro litre. An internal spring return makes the valve fully adaptable with Techcon Systems controllers. A short opening stroke provides extremely fast, positive shut-off and the external stroke control adjustment allows the operator to fine tune deposit sizes. Air pressure through the air inlet port retracts the needle assembly from the seat (tip cannula) allowing fluid to flow from the valve fluid inlet to the Luer outlet. Relieving the input air pressure allows the spring to return the needle back to its position, to close the material path, ready for the next dispensing cycle. The TS5440 Series compact design allows for mounting flexibility and integration into automated applications.
