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

The pressure reducing or regulating valve 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.

Know that at Valfonta, we have 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 regard, the experience we have gained over all these years is the best guarantee for each of our clients. We carefully study each installation, as well as the needs or requests made 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 highly suitable for gas control in the temperature range between -10 and +80ºC. It is direct-acting, without auxiliary power, and membrane-balanced. It controls the outlet pressure even in the presence of fluctuations in the inlet pressure. The valve closes when downstream pressure increases. It is well-suited for gases (air, nitrogen…), liquids, and steam. It is used in Blanketing installations.

  • Piston-operated pressure reducing valve (model PRV 20): A self-acting pressure reducing valve that is balanced by a piston used to provide a constant and decreasing pressure, despite fluctuations in the inlet pressure. It is commonly used in various applications such as chemical laboratories, sanitary plants, sprinkler systems, etc.

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

  • Self-acting pressure reducing valves (multiple models): These valves are designed to provide a constant pressure, even in the presence of fluctuations in the inlet pressure. They are especially designed to work with low outlet pressure gases, liquids, and gases from groups 1 and 2, as well as compressed air, steam, nitrogen, fuel, water, neutral gases, etc.

  • Direct-acting pressure reducing valves (multiple models): These valves are easy to regulate and can be installed in any position. They come with bellows, are self-acting, or self-compensating. They are commonly used in chemical laboratories, sanitary installations, industrial settings, steam applications, for cylinders and vulcanizing presses, as well as in furnaces.

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

Determine the inlet pressure and the required outlet pressure for your application. It is crucial to know the pressure values to choose a pressure reducing valve (PRV) that can maintain the desired pressure consistently.

Calculate the required flow rate in the system, as this will influence the size of the valve you need. Flow is measured in liters per minute or gallons per minute and is essential for properly sizing the pressure reducing valve (PRV).

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

Fluid temperature is a critical factor as it can affect the valve’s performance and longevity. Choose a pressure reducing valve (PRV) designed to withstand the temperatures it will be exposed to.

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

Determine whether a pressure reducing valve (PRV) with high accuracy and stability in the outlet pressure is needed. Some applications, such as laboratory systems or medical equipment, may require very precise regulation.

Ensure compliance with 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 pressure reducing valve (PRV). Valves should be inspectable and maintainable efficiently.

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