Solenoid Isolation Valves

2 and 3-way valves that separate the working fluid (or gas) from the metal components of the valve. These are typically used with more aggressive liquids.

LFV SERIES SOLENOID VALVES

The LFV Series is a family of 2-way isolation valves, featuring bi-directional flow and a contoured flow path which allows complete flushing. This contoured flow path also minimizes damage to "delicate" fluids. The small internal volume reduces the amount of fluid needed to fill the system (transport volume) further reducing sample and reagent requirements. LFV valves are optimized for applications in analytical instruments, biotechnology and IVD devices.

LFR SERIES SOLENOID VALVES

he LFR Series Micro Inert Valves (MIV) are 3-way inert solenoid valves designed for applications demanding high flow and small size. The different mounting combinations and porting options allow the designer the highest degree of freedom available.

• Pressure Range: 28 in.
• Hg Vac - 30 psig
• 30 ms Response Time
• 10 Million Cycles Minimum
• Power Consumption: 1.6 Watts
• 12 and 24 Volt Models
• Available with EPDM, FKM, or FFKM Diaphragm
• PEEK Porthead on all Models
• Manifold Mount, Barbed, and
• 1/4-28 Flat Bottom Boss Available

LFN SERIES SOLENOID VALVES

The LFN Series Solenoid Valves are 2-way normally closed, diaphragm valves, designed to provide consistent reliable switching in the smallest footprint possible. The small footprint allows a high valve packing density on manifolds. Combining this with the valves' low internal volume greatly reduces the overall system fluid volume and manifold size. The isolation diaphragm on an inert housing makes these valves suitable for the control of critical and aggressive fluids.

• Small size: 0.3" center to center mounting
• Low internal volume: 13 microliters
• Fast response time: 20 ms (faster with a spike and hold circuit)
• Operating pressure: 30 psig
• Low Power: 900 mW

LFY SERIES SOLENOID VALVES

The LFY Series are chemically inert solenoid valves which provide precise dispensing and control of aggressive and sensitive fluids. The LFY Series valves feature a unique internal configuration which minimizes damage to sensitive materials.

• Zero Dead Volume
• Standard (3,200 Lohm) and High Flow (1,000 Lohm) Models
• 2-way and 3-way models available
• Operating Pressures up to 30 psig
• Standard 12 and 24 vdc models available
• Low Internal Volume (as low as 18 microliters)
• Several mounting options for tube connections and manifold applications
• FKM and FFKM elastomers available
• 5 Million Cycles (minimum) service life
