Knife Gate Valve wafer type DNOVA GVKN1331E-2W-Fb-2P with pneumatic actuator and LJ12A3-4-J/EZ 220V inductive sensors designed to shut off the flow of the working medium in pipelines in sewerage systems and treatment facilities, food and mining industries. An inductive sensor is a non-contact type sensor designed to monitor the position of metal objects. They are manufactured with normally open and normally closed contacts, but there are options with both types of contacts at the same time. It works by changing the parameters of the magnetic field created by the inductor inside the sensor.
