Miniature inert solenoid valve protects sensitive fluids

21 June 2015

Lee Products' new LFY2 chemically inert solenoid valve is suitable for the rapid and precise dispensing of aggressive and sensitive fluids.

This three-way inert, zero-dead volume solenoid valve features an innovative ‘Y’ internal flow design that reduces the internal volume to a total of just 12 micro-litres.  This design also provides a clean, flushable flow path, which reduces or eliminates carry over between fluids and helps to protect fragile samples. In addition, the valve’s balanced actuation virtually eliminates pumping effects, which is common to diaphragm valves.

The electrical interface of the valve provides secondary connector retention and is compatible with standard AMP connectors. Available in 12 and 24Vdc operating voltages and with either 062 MINISTAC or standard ¼ - 28 flat bottom fluid connections, the LFY2 requires a small footprint of just 77mm (L) x 26mm (W).

The valve has a response time of less than 30ms and is designed for long and reliable operation of over five million cycles. Custom configurations, including wetted materials and porting configurations are available to suit specific OEM applications.
