How is the water pressure regulator used in the water supply system: types and methods of installation
The choice of plumbing equipment must be approached responsibly. All manufacturers' requirements must be followed. The water pressure regulator in the water supply system can prevent many troubles. Pressure surges inside the plumbing system can lead to breakage of even expensive and proven structures. In this case, a special device will help.
Control device device

Using regulators
Units that help to maintain a certain amount of pressure are used for commercial purposes and in everyday life. They have the following advantages:
Before installation, it is worth studying all the input and output elements.
With the help of a water pressure reducer in the water supply system, the movement of the liquid is stabilized, and hydraulic shocks are extinguished.
The pressure control device is an integral part of the plumbing structure
Such products are used in water supply networks for various purposes, in structures for irrigation, in water filling stations and in various fire extinguishing systems.
Installation features
This device is placed at the inlet to a residential building, behind pumping equipment or valves. The water pressure reducer in the water supply system allows dosing the pressure in the mains.
You can install the gearbox yourself
If the device has a large diameter, then a filtering device is installed to purify water. A shut-off valve is also mounted, which is necessary for ease of maintenance or repair work. Manometers are mounted on the line in front of the regulator and after, allowing for adjustment and systematic inspections.
Experts recommend mounting a pressure gauge for better device performance
When choosing a device, it is necessary to find out the permissible head loss and flow rates.
Design features and types
Before buying a water pressure regulator, you need to choose the right option.
Lever flange pressure regulator in the water supply system
The lever model restrains the excessive pressure in the pipeline network before and after the installation of the mechanism. This helps regulate the flow.
A design feature is the presence of weights
The device consists of a steel or cast iron body, a lever structure with supporting elements, rods with valves, a cover and a special mechanism with a membrane. Valves open access under the influence of loads. They help regulate the head after the installation site of the structure. The setup steps involve special weight calculations and cargo accounting.
Household regulator
The water pressure regulator in the domestic water supply system is manufactured by the Russian company Pascal. Household appliances help to extend the service life of the valve and pipeline mechanism. Also, devices can reduce noise, reduce pressure and vibration.
Household structures can have different shapes.
Installation of such gearboxes reduces costs water supply and electricity consumption.
Electronic variant
An electronic device starts a low-power pump when water is taken from the system. This mechanism is silent. A special sensor protects against possible water hammer and against the operation of the pumping mechanism without water.
Electronic products allow for high-quality system automation
The regulator consists of a special diaphragm, a plate, a sleeve for connecting to a cable and a main body element.
Electronic water pressure regulator in the apartment: how to regulate the mechanism?
Manufacturers set the optimum pressure in the design with a value of 1.5 bar. It should be borne in mind that the nominal value should be 0.8 bar higher than the starting value. The starting value is adjusted with a special screwdriver.
The installation scheme has some peculiarities

Direct acting pressure regulator
A flange valve is a product of an industrial water pressure regulator in a water supply system. The price for it varies from 30 thousand rubles. Values are adjusted using network settings.
This diagram allows you to understand how the direct action mechanism works.
The device consists of the following parts:
If the value exceeds the possible threshold, then the liquid enters the valve container. In this case, the diaphragm closes the passage opening of the regulator. After reducing the pressure, the membrane opens the passage.
Honeywell device
Household models include Honeywell. The device contributes to the economical distribution of water, and also helps to maintain constant values from the network. The manufacturer produces combined models with a regulator and filters in one housing.
The model of this manufacturer is distinguished by its convenience and pleasant design.
Regulators for apartments
The regulating mechanism will help to improve the quality of water supply in the apartment. For a residential building, you can choose a device with a throughput of 3 m3 / hour.
Appliances used for apartments have a certain device
The following rules will help to correctly install the device:
These diagrams allow you to understand how the installation of the control device is carried out in the apartments.
The principle of the mechanism
The reducer is a pressure control and regulation valve. The work of the structure is to smooth out the forces of the two types of equipment under the pressure flow. Regulators are of two types:
The advantage of such devices is practicality and reliability in operation. Subject to the settings, the mechanism is able to maintain the specified indicators.

How to adjust the device?
When adjusting the device, the installed pressure gauge helps. Turn the adjusting screw until the desired values appear on the gauge. This screw is installed on the equipment case. It can be moved with a hex key.
The product is adjusted using the mounted pressure gauge
The adjustment is made as follows:
A special adjusting knob allows you to set the desired pressure value
A high-quality filtration design is required for full operation of the device

You can purchase models from both domestic and foreign suppliers.
| Company and country | Diameter, mm | Pressure adjustment value, bar | Cost, rub. |
|---|---|---|---|
| Ikma (Italy) | 15 | 1-6,5 | 610 |
| RDV 2A-M (Russia) | 20 | 1-16 | 1200 |
| Honeywel (Germany) | 15-20 | 1,5-6 | 1900-7000 |
| Regulators EDD1 EDD5 (China) | 25 | 1-10 | 1800-2100 |
Domestic models are inferior to foreign ones in design and usability, but not in the quality of devices.
The regulator allows you to restrain the pressure head in the system, which ensures high-quality and smooth operation of the system
Installing a regulator helps to optimize the water supply system and create more comfortable living conditions.
