Brass baffle flow switch NK01B

Principle characteristics

Mechanical flow switch, with built-in spring supported baffle, triggers the fretting switch when the flow reaches the prefabricated value. SPDT output, small pressure loss, complete isolation between mechanical and electronic parts/large flow range, easy to adjust and set, the switch factory standard with a set of baffling (5 pieces), can be used flexibly according to the field, suitable for a variety of pipelines, the switch has high reliability and good repeatability, anti-pollution ability.

Product application

Gas-liquid dual, industrial automation/mechanical equipment/air compression industry/refrigeration and air conditioning suitable for diameter ≥25mm pipe.
