DESCRIPTION
FEATURES
• Leak proof body machined from bar stock
• Choice of custom vane calibrated for your application, Model V4, or field adjustable multilayer vane, Model V4-2-U (see set point chart)
• Weatherproof, designed to meet NEMA 4
• Explosion-proof (listing included in specifications)
• Installs directly and easily into pipeline with a thredolet, tee, or flange (see application drawings)
• Can be used in pipes 1-1/2½ and up
• Electrical assembly can be easily replaced without removing the unit from installation so that the process does not have to be shut down
• High pressure rating of 1000 psig (69 bar) with the brass body and 2000 psig (138 bar) with the 316 SS body
Rugged and reliable the Series V4 Flotect® flow switch operates automatically to protect equipment and pipeline systems against damage from reduction or loss of flow. The V4 is time tested being installed in thousands of pipelines and processing plants around the world. A unique magnetically actuated switching design gives superior performance. There are no bellows, springs, or seals to fail. Instead, a free-swinging vane attracts a magnet within the solid metal switch body, actuating a snap switch by means of a simple lever arm.
APPLICATIONS
• Protects pumps, motors and other equipment against low or no flow
• Controls sequential operation of pumps
• Automatically starts auxiliary pumps and engines
• Stops liquid cooled engines, machines and processing when coolant flow is interrupted
• Shuts down burner when air flow through heating coil fails
• Controls dampers according to flow
