Solenoid directional valves

Application

The solenoid valve from the Italian company "CEME" is used in heat and water supply networks, in air conditioning and water treatment systems, in industry and various agricultural production.

Description

Solenoid valves are installed in pipelines, and depending on whether they are closed or open, they block or open the flow for the working medium when the supply voltage is applied to the valve coil.
The control sensor for supplying a signal to close or open a circuit can be various devices eg pressure switch, thermostat, flow switch, float switch and the like.

Installation and operation

In the pipeline, the valve can be installed in any position, but the working medium must move in the same direction as indicated by the arrow on the body. The very best and the best option location is coil-up. It is very important that foreign particles are not allowed to enter the valve area. This can have a negative impact.
In addition, the manufacturers indicated that the solenoid valve must not be used for other purposes. For example, you cannot mount it in a structure that was not originally provided for by the developers. It is also forbidden to use the valve in media, the temperature of which is outside the permitted maximum and minimum. Because if it is used in an unintended temperature range, it may fail, resulting in an emergency.

Basic data

NBR is used as a material for the production of membranes. If a different material is required, it is possible to manufacture from FPM-EPDM upon customer request.
The body is cast in brass. Internal parts are made of stainless steel.
The working environment can be a technical or drinking water, light oil products or air. As you can see, solenoid valves can be used almost anywhere.
The electrical connection is a P65 3-pin plug. It is included in the kit.

Solenoid valves normally closed, type 86

Solenoid valves normally open, type 87

The voltage is standard, that is, AC ~ 230 Volts and AC ~ 24 Volts, with a frequency of 50 Hz.
If the client needs valves with coils designed for a frequency of 60 Hz or other voltage, then he will have to make an individual order.

Normally open solenoid valves

CEME solenoid valves

Solenoid solenoid valves CEME (Italy) are used in water supply and heat supply networks, in various industries, in water treatment and air conditioning systems. By design, they are divided into normally open- are in the open position when there is no power supply and close when current is applied to the coil, and normally closed valves- are in the closed position when there is no power supply and open when current is applied to the coil. CEME solenoid valves are installed on pipelines and open or shut off the flow of the working medium when the supply voltage enters the valve coil.
The following can be used as a control sensor giving a signal to open or close the power supply circuit of the CEME valve coil:

• pressure switch;
• float switch;
• various kinds of level control devices;
• flow switch;
• thermostat and the like.

On the pipeline, solenoid valves are installed in any position (the movement of the working medium must coincide with the arrow indicated on the body). The preferred installation is coil up. It is not allowed to get into the valves of foreign particles, as well as to use it for other purposes.

Solenoid valves occupy a significant part of the company's product range. This Italian company produces more than 20 series of solenoid valves designed to control the flows of transported media of various aggregates and varying degrees of aggressiveness.

Applications

Shut-off valves from this manufacturer can be installed in the following systems transportation of liquid and gaseous media:

• Water and steam supply lines. And for water potable quality special normally closed or open solenoid valves with DVGW seal are required, and for steam - with EPDM seal. Such fittings are suitable for an iron, for washing machine, for a vacuum cleaner powered by a household power supply (220 volts).
• Lines for supplying petroleum products. Moreover, for diesel fuel or light oil, a special FPM seal is required. It protects normally open or closed valves from leaking chemically active media that will corrode water gaskets from the first hour of operation. Therefore, the solenoid valves for diesel engines are allocated in a special series.
• Gas supply lines. Practically any normally closed or open solenoid valves can be used only for gases of inert type, for example, suitable for water (technical). And for flammable media - propane and so on - you need a special gas valve, certified according to the CEE 90/396 standard. Standard water or steam valve won't come in handy here. Moreover, for gas - fuel, you also need a special coil operating under a voltage of 12 volts or 24 volts. This voltage eliminates arcing.
• Coolant supply lines. In this case, normally open or open solenoid valves with an insert suitable for low temperature liquid or gases of any type other than ammonia are needed. Moreover, the solenoid of such a valve should work even in 50-degree frost. Although for an air conditioner or household refrigerators fittings with lower frost resistance can be used.

Where to buy solenoid valves?

In Russia, you can buy CEME solenoid valves only from resellers or at the official dealerships of this brand.

Dealers offer a limited assortment, without subsequent purchase support. Moreover, their product may turn out to be a Chinese counterfeit of the original product from Italy. In this case, it does not matter how much the product costs - its operation will cost the buyer much more than the initial expenses.

Official dealers of CEME, such as our online store site, do not dump "in spite of" competitors, but offer more substantial than low prices, Benefits.

What are the benefits of an online store website?

• Firstly, the site is the official distributor of Ceme. Therefore, we only trade in original products.
• Secondly, even specialized types of fittings can be bought in our store. The store site offers a selection of products comparable to the official site, supplied directly from Italy.
• Third, the site offers organized delivery goods in Moscow and all over Russia. In addition, delivery on order to Belarus and Kazakhstan is also possible.
