V4 series impeller explosion-proof flow switchDetailed product description：

The V4 series impeller explosion-proof flow switch is suitable for flow changes of gases, liquids, or flowing solids

Product features:
Explosion proof and leak proof;
High protection level, suitable for outdoor installation;
Suitable for pipe diameters ranging from 1-1/2 "to 20";
On site adjustable pipe diameter;
Temperature resistance: up to 205 ℃;
Pressure resistance: 350bar

Gas and liquid flow switch, leak proof and explosion-proof multi blade adjustable on site, pipe diameter 1.5-20 ", maximum temperature 205 ℃, maximum pressure 345 bar, multiple ranges, adjustable on site, 1-1/2"~20 "pipeline, explosion-proof and leak proof main body Reliable protection against flow changes or interruptions of liquids, gases, and flowing solids in pipelines Provide user specified or universal multi-layer blades that can be installed on-site on pipelines with a diameter of 11/2 "or more.

The V4 series impeller explosion-proof flow switch is designed to comply with NEMA-4 watertight structure.
Convenient 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 unique 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

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, threaded outlet or flange The swinging blade motion can accurately and persistently respond to liquid flow velocity Multilayer blades or 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; Level II E. F and G groups, CENELEC: EEXD IIB T6 (T amb.=75 ℉) IP66
CII. Zone I. Provide installation in 1? The universal or customized blades for the above pipelines are designed to comply with NEMA-4 waterproof structure
