sturdy and reliableThe V4 series FLOTECT @ blade flow switch can be used to automatically protect equipment and piping systems from damage caused by reduced or absent flow. V4 has been tested by time and has been applied in tens of thousands of pipelines and processes around the world. The unique magnetic drive switch design ensures its excellent performance, without bellows, springs, or sealing failures. On the contrary, the freely swinging blades attract the magnets in the solid metal switch body and excite the fast switch through a simple lever.

Product Features:

The main body of the leakage prevention switch is made of processed rod material

Customizable blades and models according to user needsV4, Or on-site adjustable multi-layer blades, model V4-2-U (see setting table)

24/7, designed to meetNEMA-4

preventExplosive (see specifications)

It can be conveniently installed directly on the pipeline through welded pipe threads, tee threads, or flange plates (see application installation diagram)

Can be used for greater thanOn a 1.5-inch pipeline

Electrical components can be replaced without disassembly, ensuring that the manufacturing process is not interrupted

The brass body can withstandHigh pressure of 1000 PSI (69 bar) and 316 stainless steel body of 2000 PSI (138 bar)

: Should Using:

Protect pumps, engines, and other equipment from damage caused by low or no flow rate

Sequential operation of control pumps and other equipment

Automatically start auxiliary pump and engine

When the coolant flow is interrupted, the water-cooled engine, machine, and operating process stop

Turn off the heater when no airflow passes through the heating tube

According to the flow control gate
