Description
The gate valve is designed for installation on a pipeline as a shut-off device and for regulating the flow of the working medium in water supply systems (except for drinking water supply systems) and the chemical industry.
Pneumatic distributors are used for control in pneumatic systems with a NAMUR mating surface for installing distributors through through holes in the body. Electromagnetic control is carried out using voltage coils 12-AC, 12-DC, 24-AC, 24-DC, 110-AC, 220-AC. Depending on the model, distributors have one-way or two-way control. Pneumatic distributors with electromagnetic control have a wide range of models and include common types of switching for three (3/2) and five (5/2 and 5/3) linear pneumatic distributors. Intended for use with gate valves with a pneumatic cylinder. Application is also possible on other valves with a pneumatic drive.
An inductive sensor is a contactless sensor designed to control the position of metal objects. It is not sensitive to other materials. Inductive sensors are successfully and widely used to solve many automation problems in manufacturing. They are manufactured with normally open and normally closed contacts, but there are options with both types of contact simultaneously. They work by changing the parameters of the magnetic field created by the inductance coil inside the sensor.
