JFA400 Single-track SPDT Output Industrial Flow Switch One-way Water Oil Flow Switch
Overviews
JFA400 One-way flow switch 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.
YH400 flow switch is only suitable for liquid medium above 0, 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.
Application: water treatment system, central air-conditioner, water chilling unit and etc. It is suitable for water, ethylene glycol and others liquid non-corrosiveness for brass and phosphor copper, or no influence for seal performance.
