Description
The gate valve is designed for installation on the pipeline as a shut-off device and regulation of the working medium flow in water supply systems (except drinking water supply systems) and chemical industry.
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.
