Dewell explosion-proof flow switch

Dewell explosion-proof flow switch

Simple and reliable - The V4 series FLOTECT leaf flow switch can be used to automatically protect equipment and piping systems from damage caused by reduced or interrupted flow. This magnetic drive switch design ensures excellent performance, making it widely used in thousands of pipelines and processing plants around the world. Can multi-layer blades be suitable for a size of 1? Larger pipelines can also be customized from the manufacturer. The instrument does not include bellows, springs, seals, etc. that may cause malfunctions. On the contrary, in the illustrated solid metal switch body, there is a magnet that attracts the freely swinging blades and drives the SPDT quick action switch through a simple lever.
Dewell explosion-proof flow switch

Features - A simple designed anti leakage switch body, made of precision processed rod material, capable of withstanding a pressure of 2000PSI (140kg/Cm2) and eliminating the possibility of process liquids entering the switch components. The casing cover of the threaded tube allows for easy inspection and disassembly of electronic components without opening the entire processing process. It must be done with the power cut off. The instrument can be quickly and easily installed directly in the pipeline through a T-joint, Thred-O-Let or flange. The swinging blade motion can accurately and persistently respond to liquid flow velocity. Multi layered blades or user customized blades have both sensitivity to low flow rates and strength to withstand high flow rates. If necessary, a delay timer can also be installed during the installation process. All switches are explosion-proof and listed in UL and CSA, Class I,Groups C&D； Class II, Groups E, F, and G, or set fire to CENELEC/SAA EExd IIB T6 (T Amb.=75 ℃); And it is recognized by FM.
Application - Protect engines, pumps, and other equipment from damage caused by low flow or flow interruption, control the sequential operation of pumps and other equipment, automatically start auxiliary pumps and engines, or drive alarm and signal systems. When the cooling system malfunctions, the water-cooled engine, machine, and operation process stop. When the airflow fails to pass through the heating coil, the burner stops working. According to the flow control regulator. If the coolant oil stops flowing, the machine will stop working.
Explosion proof enclosure - U.L and C.S.A. Class I, Groups C and D; Grade II, Groups E, F, and G, CENELEC: EEXD IIB T6 (T Amb.=75 ℉). IP66 CII. Zone I. provides installation in 1? The universal or customized blades of the above pipelines are designed to comply with NEMA-4 waterproof structure.
