Gems Shuttle Type Flow Switches
For Moderate to High Liquid Flow Rates
Models for flow rate settings from .5 GPM to 100.0 GPM
Rugged housings with port sizes ranging from 3/4" NPT to 3" NPT
Efficient flow paths assure low line pressure drop at full flow
Typical Applications:
Protect bearings or gears from loss of lubricant flow
Switches can reduce maintenance costs on:
Oil Separators • Fuel Systems • Pumps • Compressors • Presses
Provide instant, automatic shutdown if coolant flow falls off in electronics or machinery, such as:
Heat Exchangers • Semiconductor Manufacturing Equipment • Induction Furnaces • Radio Transmitters
Assure efficient operation of process systems, including:
Water Filtration and Reverse Osmosis • Chlorinators • De-icers • Sterilizers • Evaporators
