After pressure regulators (pressure reducing valves) are designed to regulate pressure of the working medium behind the valve and maintaining it at the given level. Pressure reducing valves should provide a stable secondary medium pressure and at the same time provide the necessary performance. Thus, pressure reducing valves automatically regulate the flow of the working medium in accordance with the needs of the equipment.

Pressure regulators “after themselves”, which are pipeline fittings that control the flow rate, will help you maintain the stable functioning of gas and water lines. These devices are simple and reliable, do not require additional energy sources and operate automatically. We recommend installing a pressure regulator "after you" in order to protect the equipment from sudden surges in the pressure of the working medium, eliminate hydraulic noise and reduce water consumption.

The pressure reducing valve provides the required parameters of the secondary flow in accordance with the characteristics of the units installed along the perimeter of the pipeline. The pressure regulator of direct action "after itself" is mounted in the pipeline by means of a threaded or flanged connection. Such fittings are made of bronze, steel, ductile iron and brass.

The principle of operation of the water pressure regulator and application features

Why do we need a pressure reducing valve, we have already figured out. Now let's look at how the water pressure reducer works.

Technical characteristics of the pressure regulator after itself:

• Diameter - from 10 to 200 mm.
• Execution - membrane or piston.
• Working pressure - 16-25 atm.
• The liquid temperature is up to 150°C.
• Setting range - 1-5 bar or 3-12 bar.

Let's pay attention to the design features that distinguish the pressure reducing valve. The spring-membrane fluid flow regulator is more often used at industrial facilities in the distribution systems of coolant, water, steam, gas, oil, formation water, air and ventilation. Since such lines tend to have a powerful pressure, a metal membrane sensing element is better suited for operation in difficult conditions.

The piston water pressure regulator after itself is widely used in residential buildings and office buildings. Valves of this design are easier to maintain and it is cheaper. On the pipelines of these facilities, the pressure of the medium usually does not exceed 3-4 atmospheres, so the piston is quite enough to provide reliable protection for household appliances and metering devices from surges even up to 12 atm.

The operating principle of the pressure reducing valve is quite simple. The sealed chamber is divided by a membrane into 2 parts. The regulator valve, taking into account the power of the incoming flow, opens or closes in order to ensure a given flow parameter in the pipeline after it. In the absence of pressure, it is completely open - this is its normal state.

Water pressure reducer adjustment

The water pressure reducer is adjusted automatically by means of an elastic membrane or a piston under the influence of an impulse line.

The installation scheme of the regulator includes:

• pressure gauges - 2 devices, placed before and after the valve,
• strainer,
• pipe fittings,
• drain valve.

Water pressure reducer - advantages:

• does not need energy sources,
• small inertia,
• work due to the energy of the working environment,
• suitability for repair
• simple operation and high reliability,
• high sensitivity,
• does not require sensors and control controllers.
