China Jfa400 Pneumatic Air Pressure Flow Control Switch Paddle Water Pump Flow Controller

Product description:

JFA400 paddle flow switch one way series is SPDT output, good performance and high
accuracy. This instrument can be installed in water pipe or other liquid tube
non-corrosiveness for copper. When liquid flow achieve a certain velocity, needn't up to
rated point, one circuit closed and another opened.
JFA400 flow switch is only suitable for liquid medium above 0ºC, it also can used
in hyper saline liquid and not in dangerous liquid.
JFA400 flow switch can installed in outdoors, in tubes horizontally or vertically.
JFA400 flow switch is only for operation and control. It require high responsibility of installer and system of limit control and alarm monitor, which can prevent control failure.
Note: flow switch can't be struck by water. If there is a quick closing valve in downstream,
it must use restrictor.
just need you tell us about your pipe size(DN), medium temperature, pressure value .and then we can suggest best product for you.
