Bürkert Type 8763 pressure regulator

When dosing quantities of very small amounts as well as managing the pressure differences between dosing cycles, closed-loop control becomes a challenge.

The Bürkert Type 8763 pressure regulator has been specially developed for low flow rates and the resulting small dosing quantities. The device is characterised by short response times and precise closed-loop control of pressure. There are no down times or rejects at the beginning of dosing cycles. The digital interface makes it possible to access the various parameters at any time in order to change settings and read out data. Whether operating filling systems or machines for genetic analysis and synthesis, a good valve alone is not enough. Precise pressure regulation is also essential for accuracy in time-pressure dosing. Only in this way can accurate dosing be implemented.

The Type 8763 offers repeatable and accurate dosing of liquids in the µL range, with a response time in milliseconds and active pressure relief for optimum control performance. Digital communication permits easy integration into a fieldbus network, and extended functionality is available through an additional sensor input and actuator output for pump or additional pressure sensor. An active vent valve also helps to minimise the consumption of costly carrier gas.
