Regulators are quite different in structure. First of all, it should be noted that there are separate models for cold and hot water. The nozzles are installed on them of different diameters, and not for all pipelines they will fit. The main brands for today are considered to be the companies "Honeivel", "Vots" and "Hers". In order to learn more about pressure regulators, it is necessary to consider the popular modifications that are presented on the market.
Devices with filters
Regulators of water pressure with a filter are considered quite common today. On average, at the inlet, they are able to withstand a pressure of 20 bar. In this case, the membranes are installed, as a rule, of a flat type. The bodies are made of brass. However, the steel modifications on the market are also represented. Handles in this case are used mainly in the form of a butterfly.
In this case, the lever regulators of water pressure are also in great demand. These modifications are most suitable for hot water. The diameter of the connecting pipes of the regulators is quite different. Also note that many models have special plates that are installed above the pins. Due to this, spring breaks occur quite infrequently.
Dual-membrane water pressure regulators are in great demand today. However, they also have shortcomings. First of all, it should be noted that at the entrance they are able to withstand the maximum pressure at 15 bar. At the same time, modifications with filters are quite rare. In addition, it is important to consider the large sizes of such models, in comparison with single-membrane analogues. Springs are most often attached to them on plates.
Corps for today in stores are found in steel type. At the same time on the scale of the model are quite different from each other, and in this situation, much depends on the manufacturer. The connecting pipes are often brass type. At the same time they have a screw connection. Directly the covers are fastened to the screws. However, models with fasteners on the market are also provided.
Three-membrane modifications are used at a pipeline pressure of more than 40 bar. In this case the springs are quite powerful. Also it should be noted that the type of plates are very different. As a rule, regulators with pins are large in size. Direct scales are set to three divisions. Filters in such devices are often used in a mesh type. The indicated regulators of water pressure (the market price) stand on average around 3 thousand rubles.
Devices of the company "Honeivel"
Pressure regulators of the above company, as a rule, are manufactured with double membranes. It should also be noted that the spools are copper. At the same time, the thrust nuts are installed quite sturdy. Immediately at the entrance, many models are able to withstand a maximum pressure of 30 bar.
If we consider regulators for cold water, then they often have a special protective ring. Thus, the spool during operation of the device takes off quite rarely. Average quality water pressure regulators in the apartment of the above-mentioned trademark stand at around 3200 rubles.
Model "Honeydel RDV"
The water pressure regulators "RDV" are ideal for piping with cold water. In this case, the membrane is used as usual. At the same time, the device is able to hold a pressure of 35 bar at the input. The gasket under the spool is in this case a rubber type. Directly fixed nut is attached to the washer. It should also be noted that this model is characterized by a sturdy body. Directly the lever moves smoothly, and to change its position of greater physical effort is not required. To install this regulator manufacturer provides a branch pipe with a diameter of 2.5 cm. The present model is currently in the area of 3100 rubles.
The water pressure regulators in the apartment of the indicated company differ, as a rule, by their cheapness. Also, it should be borne in mind that the membranes are rather flat, and they will not withstand much pressure. Install them more appropriately for cold water. Springs in this case with protective rings. Directly laying under the spools are used the most diverse. Stand on average, these water pressure regulators are 2800 rubles.
Description of the devices "VTS DVR20"
These water pressure regulators "after themselves" to date are not particularly in demand. First of all, it should be noted that the membrane in them is of a double type. Thus, this model is large in size. It is also important to mention that the spool is in this case flat, and can not withstand the heavy loads.
The lever is quite comfortable. Switching the cap is smooth. The piston in this regulator is installed without a protective ring. It should also be noted that the spring in this model has a diameter of only 0.5 mm. Stand presented water pressure regulators "after themselves" in the market of about 2500 rubles.
Differences of models "Hers"
Regulators of the trade mark are most often installed in hot water. On the arrangement of the piston mechanism, they are quite different. It should also be noted that the spools in the devices are installed in different thicknesses. Thus, the input pressure parameter of the models may be quite different. In this case, the body is most often used steel type.
In turn, the spools are usually installed copper. Brass analogues are rare. In addition, it should be mentioned that the gaskets under the springs are mainly rubber. Their wear and tear is quite small. In this case, the protective rings over the pistons load can withstand greater. The average water pressure regulators are represented by the trade mark 3300 rub.
Parameters of the regulator "Hers M6"
These regulators are most often installed on pipelines with a maximum pressure of 40 bar. Also note that they are suitable for cold water. The spools in this situation are rather flat. The membrane is of a double type. In terms of dimensions, this controller is rather compact. It should also be noted that the gaskets are wide, and they are able to withstand large loads.
Pistons for switching - brass type. Nuts for fixing are used with the M6 marking. In this case, the nozzles are manufactured in a threaded factory for screw connection. The spools in the body are fixed with a protective ring. This model is worth about 3100 rubles.
