Techcon Systems, a product group of OK International and a leading provider of fluid dispensing systems and products, showcased its precision valves at the MD&M West Conference and Expo held in mid-February at the Anaheim Convention Centre in Anaheim, CA (US).

The precision valves on display included the TS7000IMP which uses a feed screw (auger) to dispense fluid with a rotary displacement action, allowing ultra-precise control of the dispensing process. The valve’s modular design allows quick and easy replacement of the feed screw/chamber cartridge assembly without the need to remove the valve from the machine. Additionally, the valve housing is interchangeable to be used with TS5000DMP feed screw inserts. 

Also on display was TS5000DMP which dispenses material with a rotary displacement action using a rotary feed screw principle. The disposable feed screw inserts are replaced without the need to remove the valve from the machine. During operation, air pressure pushes the material from the syringe into the feed screw chamber. As the feed screw rotates, the material travels between the threads and out of the dispense tip. The feed screw is driven by the DC motor. 

The company also showcased the TS5440 Microshot Needle Valve which is said to the excellent for dispensing low to medium viscosity materials 1-100K cps in very small deposits down to 0.05µl. This valve can be controlled by a time/pressure controller.
