G G E E M M S S C C O O PISTON TYPE FS-150 Series Straight Flow Path with Low Pressure Drop Flow Rate Settings: Liquids: 0.5 GPM to 5 GPM Port Size: 1/2 NPT Primary Construction Material: Polypropylene Setting Type: Fixed These slim, inline switches reduce pressure drop to a minimum. They incorporate a unique, dual-diameter, internal bore and piston configuration to minimize flow Patent constriction. Liquids are able to smoothly pass around the piston and flow through 4.996.396 U.L. RECOGNIZED the switch with little pressure loss to the down stream line. FILE NO.
