Miniature Inert Solenoid Valve Protects Sensitive Fluids

publication date: Aug 25, 2015
author/source: Lee Products Ltd

Lee-LFY2 Valve

Rapid and precise dispensing of aggressive and sensitive fluids is a critical requirement in many OEM applications and miniature component specialists LEE PRODUCTS have an outstanding reputation for developing solenoid valves which excel in these situations.

Their LFY2 Chemically Inert Solenoid Valve is a good example of this as a recent addition to their field-proven Y-Valve range.

This 3-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 24 VDC 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 30 ms and is designed for long and reliable operation of over 5 million cycles. Custom configurations, including wetted materials and porting configurations are available to suit specific OEM applications.
