Description
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.
Pneumatic distributors are used for control in pneumatic systems with NAMUR docking surface, for installation of distributors through holes in the body. Electromagnetic control, is realized by means of voltage coils 12-AC, 12-DC, 24-AC, 24-DC, 110-AC, 220-AC. Depending on the model, the valves have one-way or two-way control. Solenoid operated pneumatic valves have a wide range of models and include common switching types for three (3/2) and five (5/2 and 5/3) line pneumatic valves. They are intended for use with gate valves with pneumatic cylinder. It can also be used on other pneumatically actuated valves.
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.
