The installation of plumbing equipment in a home, business or municipal institution is usually carried out in accordance with all rules of maintenance and operation. Most consumers purchase plumbing fixtures from reliable manufacturers, but some factors can damage any fixture. For example, changes in water pressure in the water supply system often cause equipment breakdowns. To solve this problem, it is worth installing a water pressure regulator.
A regulator, or water pressure reducer (WPR) is a special regulating device for plumbing that maintains normal water pressure. Sudden changes in pressure can not only ruin expensive equipment, but also damage repairs in an apartment or house, which leads to new expenses. The gearbox mechanism is able to reduce the fluid supply force to a normal level and prevent water hammer.
There are two types of RDV design, differing in the direction of regulation:
The principle of operation of both types is to change the cross-section of the valve. At a stable pressure that does not exceed the norm, the working valve is kept open. Minor surges cause the valve to automatically close, which reduces the pressure and reduces the risk of breakage of drainage pipes.
Also, gearboxes, depending on the manufacturer and purpose, are equipped with additional elements - air valves, filter, pressure gauge, ball valve.
Hot and cold water regulators are static and dynamic. The former maintain a set pressure level on a constant basis, the latter are designed for continuous water supply and flow. Gearboxes are used in domestic and industrial municipal water supply, at pumping stations and in fire services, as well as at water filling stations and land reclamation stations.
Modern stores offer the purchase of water pressure reducers of any type and purpose. There are several classifications of types of RDV.
Regulators that differ in their internal structure and operating principle:
Types of regulators according to control method:
Piston reducer it operates from springs, a piston and a valve, which, depending on the pressure, control the operation of the spool. The advantages of this design are affordable cost, ease of installation and a simple, reliable mechanism. Among the disadvantages, it is worth noting the high sensitivity to dirt and friction of parts.
Diaphragm reducer characterized by increased throughput, excellent performance and long service life without breakdowns. The device operates from a spring-loaded diaphragm, which is located in a special sealed compartment. Such devices have a high price, but it is justified by powerful technical characteristics.
There are also flow regulators, which are rarely used but have good properties. They do not have a moving mechanism - the internal structure consists of numerous ducts and compartments. Water entering such a labyrinth slows down the speed of movement, which reduces its pressure and protects the plumbing from water hammer.
Regulator type | Connection Diameter (inch) | Pressure adjustment limits (Bar) | Throughput (m³/hour) | Nominal water flow (m³/) |
With filter and pressure gauge | 1/2 | 2-5 | 1,40 | 0,95-1,27 |
With filter and pressure gauge | 1/4 | 2-5 | 2,44 | 1,70-2,27 |
Flow limiter | 1/2 | 2-4 | 1,98 | 0,95-1,27 |
Membrane | 1/2 | 0,5-7 | 1,85 | 0,95-1,27 |
Membrane | 3/4 | 0,5-7 | 2,60 | 1,70-2,27 |
Piston | 1/2 | 1-4,5 | 1,60 | 0,95-1,27 |
Piston | 3/4 | 1-4,5 | 2,61 | 1,70-2,27 |
Piston | 1 | 1-4,5 | 3,34 | 2,65-3,53 |
Piston | 1 ¼ | 1-4,5 | 4,89 | 4,34-5,79 |
Piston | 1 ½ | 1-4,5 | 7,85 | 6,78-9,00 |
Piston | 2 | 1-4,5 | 10,8 | 10,6-14,1 |
Piston with pressure gauge | 1/2 | 0,5-5,5 | 1,6 | 0,95-1,27 |
It is recommended to trust the installation of the water pressure reducer to specialists and experienced craftsmen. This is the only way to guarantee reliable, long-lasting operation of the device without unscheduled repairs. If you have practical experience in installing plumbing fixtures or measuring equipment on pipes, you can install the RDV yourself.
The procedure for installing the gearbox in an apartment:
Installation of the RDV in a private country house differs slightly from that in an apartment. To prevent water hammer and breakdown of plumbing equipment in the house, you should install the regulator immediately behind the meter, and then install a check valve, filter and faucet.
To choose a reliable device for regulating water pressure, you need to know some parameters that should be taken into account:
If you have a choice whether to install a water pressure regulator or not, the answer is clear - install it. The device fully justifies its cost, and consumers note many advantages of installing the RDV:
The Russian market offers a huge range of water control devices from various manufacturing companies. Over many years of sales, some of them have proven their authority and competence in the manufacture of RDV.
It is also worth noting such leading global brands as FADO, DANFOSS, GIACOMINI, EDD, ALTAIS. Engineering and communication products from VALTEC are especially in demand, as they are distinguished by stable technical characteristics, long service life and affordable prices. You can buy VALTEC water pressure regulators from us, the official representative of the brand.

Regulator water pressure - a little protector of plumbing fixtures!
Water pressure regulators are designed to stabilize and reduce pressure in the water supply system. A pressure reducer is an important element in the system, it is a protective device; for example, let’s compare it with a 220-volt network voltage stabilizer; the stabilizer protects electrical appliances from sudden power surges in the network, and the water pressure reducer protects plumbing fixtures and household appliances (washing machines , drinking water purification filters, water heaters, etc.).
Requirements for installing water pressure reducers:
Installing a pressure reducer is quite simple, the main thing is to adhere to the following rules.
Setting the water pressure

Diaphragm and piston water pressure regulators - what are the differences?
Mmembrane regulator pressure thanks to the presence of a compensation chamber and an overlapping membrane, allows you to obtain a stabilized outlet water pressure at the outlet.
The main advantages of such gearboxes are:
Piston water pressure reducer in its design it contains a piston, which is pressed by a spring. Depending on the pressure of the water at the outlet, the piston presses the passage that releases the water to the outlet.
Features of piston water pressure reducers:
NEW New addition to our range of water pressure reducers - diaphragm reducers from the manufacturer OFFICINE RIGAMONTI(Italy)
Distinctive features of membrane regulators OR series 0028:
Company OFFICINE RIGAMONTI, abbreviated (OR) previously produced membrane water pressure reducers for companies VALTEC, model VT.085.N, which has proven itself well. Plumbers and installation companies enjoy using these products to this day, but pressure reducers VALTEC do not have detachable connections, which in turn greatly simplifies the installation and subsequent maintenance of devices.
In water pressure regulators, the function of detachable connections is implemented. The basic set includes American 1/2x3/4", This functionality was previously available only in premium gearboxes, for example pressure reducer FAR HP-HP series FA 2810 or pressure reducing valve Honeywell D06F B. But the cost of such models is significantly higher than that of gearboxes from the manufacturer OFFICINE RIGAMONTI, while the permissible maximum temperature is FAR And Honeywell70°C, What 10°C less than OR gearboxes, there is an acceptable temperature 80°C , the safety margin of OR membranes adds reliability to the water supply system.
