Pressure reducing valve

What is the function of this valve as a pressure reducing system?

The pressure reducing valve or regulator is a fluid control valve, whose main mission is to reduce the outlet pressure of the system, regardless of variations in inlet pressure or demand in the line.

Valfonta has been manufacturing and designing this type of pressure regulating valves for fluid systems for over fifty years, and it goes without saying that they are our main specialty.

In this sense, the experience we have acquired over all these years is the best guarantee for each of our clients. We study each installation carefully, as well as the needs or requests you make to us, until we find the optimal solution and the most suitable valve.

Types of valves you will find in our catalog

  • Pressure reducing valve (model M2): it is very suitable for the control of gases in the temperature range between -10 and +80ºC. It is direct acting, without auxiliary energy and compensated by a membrane. It controls the outlet pressure, even if there are oscillations in the inlet pressure. The valve closes when the downstream pressure increases. It is very suitable for gases (air, nitrogen…), liquids and steam. It is used in Blanketing installations.

  • Piston pressure reducing valve (model PRV 20): self-activated pressure reducing valve that is balanced by a piston used to provide a constant and decreasing pressure, with oscillations in the inlet pressure. It is often used in various applications such as chemical laboratories, sanitary plants, sprinkler systems…

  • Self-actuated pressure reducing valves (model M1): it is actuated by a membrane that controls the outlet pressure. It does not require auxiliary energy and is very suitable for working with steam, although it is also used for compressed air, liquids and non-hazardous gases.

  • Self-activated pressure reducing valves (various models): these valves are designed to provide a constant pressure, even if there are oscillations in the inlet pressure. They are specially designed to work with gases at low outlet pressure, liquids and gases of groups 1 and 2, as well as with compressed air, steam, nitrogen, fuel, water, neutral gases…

  • Direct acting pressure reducing valves (various models): these are easy to regulate valves, they can be installed in any position, there are bellows, self-actuated or self-compensated. They are often used in chemical laboratories, sanitary, industrial, steam installations, for cylinders and vulcanizing presses, ovens…

How to select the pressure reducing valve
suitable for a specific application?

Determine the inlet pressure and the outlet pressure required for your application. It is essential to know the pressure values to choose a PRV that can maintain the desired pressure constantly.

Calculate the flow rate required in the system, as this will influence the size of the valve you need. The flow rate is measured in liters per minute or gallons per minute and is essential for correctly sizing the PRV.

Make sure you know the type of fluid that will flow through the valve, as this will affect the material of construction required. Some applications may require materials resistant to corrosion or specific chemicals.

The temperature of the fluid is a critical factor, as it can affect the performance of the valve and its longevity. Choose a PRV that is designed to withstand the temperatures to which it will be exposed.

Consider the environmental conditions, such as exposure to the weather or aggressive environments. Adequate protection and corrosion resistance are important in these cases.

Determine if a PRV with high precision and stability in the outlet pressure is needed. Some applications, such as laboratory systems or medical equipment, may require very precise regulation.

Make sure you comply with the regulations and standards applicable to your industry or region. Consult with valve experts or engineers to ensure compliance with specific requirements.

Consider the accessibility and ease of maintenance of the PRV. Valves should be able to be inspected and maintained efficiently.

In complex or critical cases, it is always advisable to consult with valve experts or specialized engineers. They can provide personalized recommendations based on the exact needs of your application.
