What is Solenoid valve?

A solenoid or solenoid valve, as well as one of the Bag Filter components, controls both the flow and flow conditions. In most types of electric valves used in industries, the flow or flux of the fluid or gas flow can be controlled by stimulating a boom or a solenoid and moving the spool upward. Solenoid valves or electric valves are divided into different types such as diaphragm valves, needle valve with application, different pressure tolerances and different types of …

A wide range of electric valves for fluids such as steam, water, air, oil, diesel, oil, gas, etc. are used in industries that are used as a simple method for disconnecting and transmitting fluid fluid remotely. . A solenoid valve is an electromagnetic device that opens or closes through an electric current through an electric coil and flushes it and, depending on the type, size, pressure and temperature, and how it operates, as well as the number of input and output ports in different ways It is categorized.

Pneumatic hydraulic valves for controlling jacks and … used in automatic irrigation systems and home appliances such as washing machines for medical purposes, such as dental chairs.

The following is a general introduction of the types of solenoid valves in terms of performance and application

Directional solenoid valve The electric valves used in hydraulic and pneumatic systems The well-known direct current solenoid valve has more than two ports for entering and exiting the fluid, while the number of states can be more than two states, for example, a milk 2/2 with There are two statuses and three ports that we will provide in the hydraulic and pneumatic sections.

Direct acting

A direct-acting direct-acting valve that directly and directly closes the fluid path and does not require a difference in pressure between the inlet and outlet and in practice operates a small amount of fluid flow, and with most fluids Aram is used for water, air, steam, oil, or any fluid that is compatible with parts in or in contact with the fluid, and functional doors include a coffee cartridge distribution unit, air dryer, sauna and vacuum systems.
In the following figure, you can see the function of a 2/2 normal close-up valve directly.

Pilot operated

A solenoid valve is composed of two separate compartments separated from each other by a diaphragm, and the aperture is not connected to the magnetic piston, which can be distinguished from the direct or direct model. It is called a pilot or indirect pilot valve The simple language uses the pressure of the input line to hold the valve and in practice, with less energy, it gives more volume than the flow of fluid.

Pilot Operated with assisted lift

In this model, there is something between direct performance and the function of the pilot that the aperture is connected to the piston and when the boom is stimulated, at a low pressure aperture it is directly separated from the corresponding part and at higher pressures of the diaphragm it is displaced by the internal pressure of the milk. Assisted lift valves can operate at zero pressure differences, however, they can not be produced normally. For example, a diesel fuel tank that feeds through the head of the tank can be used to prevent the pressure of the tank to stimulate the milk in a pilot state and to close the diesel fuel by means of an assisted lift pilot operated valve. Of course, it is better to use the Viton Bottles for this purpose. It can also be used in low-pressure cubicles or in a swing-to-zero pressure.

Also, because these lions do not require a difference in pressure for operation for vacuum or vacuum systems

To select the appropriate electric valve, consider the following factors:

Maximum and minimum linear pressure in which the solenoid valve is placed
Maximum and minimum differential pressure between the input and output of the valve
Maximum and minimum flowing through the valve
Specific gravity, viscosity and fluid type in terms of corrosivity and …
Ambient temperature and fluid

Material or both of the functions of the cone (separator and material transmitter), such as the installation of a dripping device after a variety of grinding equipment.

The profile of electric valves for dredging equipment is as follows:
Valve with sizes from 1 to 3 inches and 24 VDC, 24VAC, 110VAC, 220VAC, Nitrile resistant diaphragms for all environmental conditions and the use of Rituna diaphragm for high temperature applications (up to 200 ° C). Various inputs and outputs depending on the user’s The customer’s requirement is threaded, pressure fitting or flange inlet / outlet 90 ° or 180 °, suitable valves for cubic tanks and individual valves for specially designed piloting solenoid vessels connected to a valve or separate pilot, and the possibility of using a pilot box.
