Gate gate valve with through knife is designed for installation on pipelines as a shut-off device and controlling the flow of medium with high concentration of solid particles. It can also be used in gravity feed systems for solid and powdery substances, as the cutting edge of the knife allows cutting off high density flows.
Induction sensor is a non-contact type sensor designed to control the position of objects made of metals. It is not sensitive to other materials. Induction sensors are successfully and widely used to solve many problems of process automation in production. They are manufactured with normally open and normally closed contacts, but there are variants with both types of contact simultaneously. They work by changing the parameters of the magnetic field created by the inductance coil inside the sensor.
