The Lee Company has launched its new miniature precision fluid control component called the LFV Series 8000 2-way inert solenoid valve.

The miniature valve is used for critical flow applications in clinical chemistry, flow cytometry and haematology machines.
The normally closed (NC) inert LFV valves provide an on/off function in a critical fluidic circuit ensuring zero dead volume and low internal volume. They incorporate a diaphragm seal that isolates the fluid from the inner components to provide a switching performance. They are also rated for bi-directional flow and feature a contoured path design.
The valves small size ensures a more compact instrument footprint and means less fluid is needed enabling closer valve spacing. The product also aims to offer; long-life operation contributing towards reduced maintenance and lower installed cost, low power consumption ensuring less heat generated and a smaller power supply.
They are flow rated at 1250 Lohms maximum and pressure rated at vacuum to 30 psi and are available with push on ports for soft tubing or two manifold mount styles, which now use O-rings instead of gaskets made from the same material as the diaphragm.
LFV valves are generally used in medical and scientific applications including in-vitro diagnostics, human genomics, biotechnology, environmental analysers and other critical OEM devices.
