2 Part name Part number manifold mount above, ports at 90 degrees manifold mount above, ports in-line tube barb manifold mount below Latching, manifold mount above, ports at 90 degrees Latching, manifold mount above, ports in-line Latching, tube barb Latching, manifold mount below Description The is ideal for integration into microfluidic systems due its very small size and ultra low internal volume of 1.1µl (for valve Part Nos , , and ). The miniature solenoid is 4.2 mm square, enabling valve mounting area and flow path lengths to be minimised. The perfluoroelastomer diaphragm and PEEK body ensure that the fluid only comes into contact with inert materials. There are manifold mount and tube barb connection options. Part No ( ) ports at right angles to mounting holes Part No ( ) ports aligned with mounting holes Part No ( ) tube barb s_product datasheet Page 2 of 7

3 Main Benefits Very small footprint and package size Ultra low internal volume Excellent chemical resistance (wetted materials PEEK and perfluoroelastomer) Various mounting and tube connection options available Pressure range up to 1 bar Light weight Ideal for integration into microfluidic systems Latching version available to keep valve open without energizing (low power) Minimal thermal influence on environment with latching version Specifications - Specification Coil Type Valve Type Standard Solenoid 2-way N.C.

4 Specifications -, Latching The latching versions of the are contained in the table below. These valves require no power to maintain the valve in the open position. Power is required during the changing of state from open to closed or closed to open. The polarity of the current should also be reversed to change the state.

5 Specification State: Closed to Open State: Open to Closed Current Polarity to Change State for Latching Valves ( , , , ) Blue lead = +ve, White lead = -ve Blue lead = -ve, White lead = +ve Technical Notes: (1) Tube barb allows connection to flexible polymer tubing with for example 0.8mm ID and 1.6mm OD. (2) Duty cycle is the percentage of time that 5V can be applied to the valve without damage. (3) Maximum energising time is the maximum continuous length of time that 5V can be applied to the valve without damage. (4) Coil temperature increase indicates the heat rise in the valve coil when 5V is applied for the maximum energising time. (5) Energising time for the latching valves is the required time that voltage should be applied in order to change state. s_product datasheet Page 5 of 7
