Part of the micro fluidics range, this whisper quiet plunger type valve measures just 7mm wide and boasts a switching time of less than five milliseconds, as BME explains.

Designed for medical applications (such as drug delivery systems, in-vitro diagnostic work and precision inkjet printing) the Type 6712 WhisperValve from Bürkert has a very low switch noise of less than 36 dB. Barely a whisper, as the name suggests.[/vc_column_text][vc_row_inner][vc_column_inner width=”2/3″][vc_custom_heading text=”Bürkert’s Type 6712 Whisper Valve” use_theme_fonts=”yes”][vc_column_text]Medical equipment such as dialysis machines and drug delivery systems are very often in close proximity to the patient and may be required to operate day and night. So the Type 6712 Whisper Valve’s near silent operation is a major benefit that minimises any disturbance to the patient. The internal design of the valve also delivers an excellent cleaning cycle, which guarantees the removal of one fluid before the next process begins.


Work within the in-vitro diagnostics (IVD) sector helps to detect diseases or infections by using a controlled flow of reagents to determine a diagnosis. Automated equipment relies on built-in cleaning systems to flush the critical paths with cleansing solution between each sample. The combined attributes of the Type 6712 Whisper

Valve therefore make it an ideal component for IVD machines.


Excellent media separation and flushability


The new valve raises the bar in terms of miniature valve design by combining a host of features that make it particularly well suited to micro dosing applications in the medical sector, as well as others requiring compact, precision valves with excellent media separation characteristics. Designed with a minimal internal volume of just 5 µl, the WhisperValve has excellent flushability and can be specified with sealing materials that offer high levels of chemical resistance.


Life cycle in excess of 30 million switching cycles


Reliability and efficiency are key components of the design, with a life cycle in excess of 30 million switching cycles, under laboratory conditions, and excellent media separation which ensures no contact between the actuator and the medium. The actual service life achieved will depend on the type of medium, temperature, pressure, seal material and the specific operational conditions of the application that the valve is used in.


Efficient power consumption and fast actuation


Power comes from either a 12 or 24 VDC supply and consumption is just 0.9 Watts, which is very efficient considering the speed of actuation and the near silent operation. The response time for this valve is fast, which, combined with the low internal volume and small orifices, provides a very accurate micro-dosing capability.


With output pressure measured at one bar and an ambient temperature of 20 °C according to DIN ISO 12238:2001 the response time is just one ms (with a pressure build-up 0-10 percent) and five ms with a pressure drop of 100-90 percent.[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/3″][vc_single_image image=”2155″ img_size=”full” alignment=”center”][/vc_column_inner][/vc_row_inner][vc_column_text]Speak to BM Engineering Supplies today about our complete range of Bürkert instrumentation by calling 0141 762 0657 or email sales@bmengineering.co.uk[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_video link=”https://www.youtube.com/watch?v=RuMMBWhKKqU” align=”center”][/vc_column][/vc_row]
