General

Whereas standard ChipShop connectors only accept soft-walled tubing, this set of connectors allows connecting any 1/16" OD rigid tubing to a ChipShop chip.

Suitable for rigid tubing (PTFE, PEEK, etc.) with an OD of 1/16" (1.6 mm). Manufactured in blue TPE, max. pressure of 3.2 bar with a 1/16" OD PEEK tubing.

Plugs to block unused ports are also available in our shop.

Bürkert Whisper valve 6724 2/2 way bistable combines high chemical resistance, very fast and silent switching (3 ms at 30 dB(A)) and high back pressure tightness in a compact design of only 8.9 mm width.

This valve is either available with a Bürkert flange for connection to a manifold, or threaded 1/4-28 UNF version for tighter connection with fittings.

Connector with flying leads available for direct electrical connection.

General

A compact and light solenoid valve for various applications, from medical to aerospace. Thanks to its small size, it can be easily integrated into complex systems or used to manipulate low fluid volumes. The 6724 is on/off or proportional: use it as a standard 2/2 way impulse valve, or to control the flow rate if necessary.

Rocker valve with separating diaphragm
High chemical resistance: body in PEEK or PPS, seal in FFKM or KFM
Compact design: 9 mm width (valve only)
Orifice diameter: 1.2 mm
Switching time of 3 ms, switching noise < 30 dB(A) and power consumption < 1 W
High back pressure tightness
Excellent cleanability
100% duty cycle
Voltage: 24V DC
Port connections with Bürkert flange for the connection to a manifold or 1/4-28 UNF for easier connection to the fluidic line or Tube connector
