What is a watering solenoid valve?

A solenoid valve is a part used to open and close the coolant valve. A programmer will allow, in a fully automated way, to switch on or off the water supply.

To simplify, it is nothing more or less than an electric tap used for automatic sprinkler systems.

The solenoid valve, in addition to this automation aspect, makes it possible to differentiate watering zones for an individual supply, really adapted to the water needs of each zone.

Thus, your solenoid valve will allow you to water the vegetable garden from 2 a.m. to 3 a.m., for example, in a gentle drip manner while a rotating jet will generously and roughly water your lawn from 10 p.m.

The solenoid valves will be located on the surface (in your garage for example) or buried in a manhole. Everything will depend on the type of facility you wish to own.

A wireless remote control water valve is not an expensive material, for about fifty euros you will have a quality material. Of course, each watering channel requires a separate solenoid valve. Large lots are thus equipped with several.

Operation of a solenoid valve

Few people are familiar with solenoid valves, their principle and how they work. However, they are most often the essential vector of good underground watering.

A solenoid valve opens and closes according to the commands it receives from the wireless remote control and is positioned at the start of each network.

The solenoid valves work in 24 Volts, their supply is made by means of two electric cables. One is connected to the programmer, the other is called “common” and is connected to the other “common” (if there are other solenoid valves), then to the neutral of the programmer (most often marked “common 1″).

In the closed position, water passes through the calibrated orifice and fills the upper chamber. The diaphragm surface being large and made of a flexible material, it is placed on the diaphragm seat keeping the valve closed.

To open the solenoid valve, it is necessary that the solenoid receives an electric current, this will create a magnetic field which will raise the plunger core. In this way, water will flow through the discharge port. The water in the upper chamber is drained and the pressure drops.

The water from the network contained upstream of the solenoid valve can thus compress the diaphragm spring and allow the water to pass through.

The solenoid valve will remain open as long as the solenoid remains powered. When the programmer cuts the power supply, the solenoid core is released, coming from the discharge port, the water fills the upper chamber again and closes the valve.

Most solenoid valves can be operated manually. This principle is based on a purge that releases the water, the pressure decreases, the diaphragm lifts and the water circulates.






How does an automatic shutter work?

Roller shutters, also called roller shutters, are types of aluminum or PVC shutters, which have been in existence for more than sixty years and were initially operated manually. They generally consist of an apron; a box that is embedded in the wall for new constructions and installed either inwards or outwards for old premises; slats and slats and they are operated by wires or chains. Thanks to modern technology, however, the roller shutters have been renovated because they have been motorized and equipped with various types of locking and remote control systems. This has resulted in what are called automatic flaps.

Like any device that works automatically, a roller shutter needs a motor to be able to operate without being operated by hand. This motor is normally a tubular motor consisting of two windings, a capacitor, a reducer and mechanical stops. The connection has already existing switches and is made from four cables including phase one for the rise, phase two for the descent, the neutral cable and the earth cable. It should be noted that any installation should preferably be done by professionals to avoid any accident, and it should also be noted that the power must be completely cut off at the time of the intervention. In addition, special standards developed for the supply of roller shutters require that the supply circuit in question must be either a 16A circuit-breaker if it is a 1.5mm² section; or a 20A circuit-breaker if it is a 2.5mm² section. Consequently, the roller shutter would be equipped with a wireless remote control that would save the owner time and energy since it is no longer necessary to walk around the house every morning and every night to open or close the shutters.

Comfort and safety are also better guaranteed thanks to the use of a remote controlled electric motor. In other words, different types of remote controls can be used: remote controls with a single channel that can only manage one roller shutter at a time; multichannel remote controls that, as the name suggests, can control several devices at the same time; wireless wall controls; and programmed remote controls that operate according to pre-established times or schedules.

Types of roller shutter connections

Three cases are possible when connecting automatic shutters. In the first case, the wired roller shutter must be connected, i.e. either a single stable single-pole switch or a stable PM3 switch must be used. In this way, only one roller shutter is connected to the single pole shuttle and it is finger controlled when pressed. Two positions are possible: a stable position of the button that raises or lowers the roller shutter and a central position that stops the shutter. The second case involves connecting two roller shutters to a single button on a single unstable bipolar switch. Indeed, the two poles of the inverter allow the two roller shutter motors to be connected and operated simultaneously. As soon as you stop pressing it down, the roller shutters stop quickly.  Finally, in the last case, a roller shutter must be connected to two or more control points; this requires the use of a remote switch, a key box and push buttons. The remote switch sends an electrical pulse to the motor each time one of the push buttons is pressed.

To go even further, there are currently connected roller shutters that are at the cutting edge of technology and through which operation is via the Internet. Therefore, all computer devices that can be connected to the Internet such as the computer, smartphone or tablet can remotely control the closing or opening of the roller shutters thanks to a server and a box (or control unit) that transmit the control information and automatically program the shutters. Apart from that, there are also solar roller shutters that work by capturing solar energy through a photovoltaic panel and that are located on the trunk of the shutters.






The advantages of choosing a ceiling fan with remote control

When purchasing a fan, you must consider certain criteria, including blade size, tilt and speed of rotation. You should not neglect the appearance and design of the unit so that it can blend into the décor of your home. Some elements are to consider for your comfort and for this you need to see the features. You have to ask yourself if you should take the ceiling fan with a remote control would be more suitable. Even if the price difference is not important between a simple model and a model equipped with remote control, we will give you the advantages that the fan equipped with a remote control could bring you.

A remote control for two functions

This type of fan is composed of a lighting system and a ventilation system. Even if these two elements are independent, you can control them from a single remote control. Indeed, this model of fan is delivered with only one remote control to ensure two functions. Once the remote control is in the hand, you can turn the fan on and off. On this same device, it is also possible to turn the light on and off, which is very practical.

A remote control for comfort in use

Even if the remote control ceiling fan is equipped with a wired release system, you do not always have to use it to turn the unit on and off. You can also use the rf remote control, which is very comfortable. When you’re on your couch, you won’t have to get up to turn off the ventilation. Just have the remote control handy to activate and deactivate the system whenever you want. If the range of the remote control is large, you can even turn on the ventilation from another room. This device will avoid you any displacement.

One remote control to adjust multiple features

On this remote control, there is not only the stop and start button. It also offers the remote control ceiling fan user the possibility to control the rotation speed and oscillation. If your fan incorporates other features, you can adjust them remotely from your remote control without having to travel. This last advantage meets the comfort requirements. If you want to prioritize your comfort in use, it is preferable to choose a ceiling fan with remote control. Some fan models are even equipped with a programming device.
