Characteristics and peculiarities of this type of valves

A steam pressure reducing valve is an essential component in steam systems, designed to regulate steam pressure at a safe and constant level.

By automatically adjusting the steam flow in response to changes in outlet pressure, these valves protect equipment, ensure operational efficiency, and maintain optimal working conditions.

Their use is critical in industries that rely on steam for heating, industrial processes, or power generation, ensuring safety and reliability in the system.

At Valfonta, we have been manufacturing various steam pressure reducing valves for many years. Thanks to our extensive experience, we know that we can guarantee the quality of our products, so that customers obtain an optimal solution for all types of fluids, whether they are steam, liquids, or gases.

Likewise, we are committed to innovation and technological development, which have marked our growth and our way of working for years.

Pressure reducing valve

Characteristics of a pressure reducing valve

The pressure reducing valves made of stainless steel have been specifically designed to reduce or modulate the pressure of piping or a system. To adjust a pressure reducing valve of steam are required certain materials and objects which are available in our web page.

These are self-powered valves that do not need auxiliary energy to start that can also be used for regulating flow or as overpressure valves. In our catalogue you can visualise the different sizes available as well as the materials they are made of and the required connections.

Functioning of the pressure reducing valves for steam

The most basic reduction of pressure only requires a simple globe valve in a fixed position, partially opened. Another option is inserting a plaque with a hole in the steam flow to keep it from fully closing.

However, any fluctuation that disrupted the flow would generate an alteration in the pressure. To avoid this situation, the pressure reducing valves (PRV) can be used to provide a precise pressure control. The quantity of valve opening is adjusted automatically to allow the pressure to stay the same in spite of the fluctuations.

Pressure reducing valve

The pressure reducing valves are valves for hydraulic control which main function is reducing high pressure in the upstream in the valve to gain much lower values in the downstream continuously. 

All of it without taking into account the variations of pressure obtained and the change that happened or will happen.

The functioning of the pressure reduction valve triggers when the door of the valve closes after detecting that the pressure in the upstream is being transmitted entirely to the superior cavity situated it inside of the valve.

This action can be triggered manually by closing the valve’s door located over the control circuit between the pilot and the P2.

Types of pressure reducing valves and pressure regulators

The most important pressure reducing valve that we offer in Valfonta are the following:

  • Direct-acting pressure reducing valves

    That can be installed in every position (they are compact and light). In this category there are relief valves with blower, self-powered valves and even auto compensated.

  • Pressure reducing valves with baffle and steam trap

    These valves provide steam or dry air with a stable secondary pressure, which improves the quality of the products and the efficiency of the heating. The opening and closing of the pilot valve are controlled by the balancing of the spring forces and the secondary pressure obtained.

  • Pressure reducing valves without separator and bleeder

    Generally used. Depending on the type of model used, the set point is set locally or remotely.

For any inquiries about steam pressure reducing valves, please contact us.

Determining the necessary pressure valve is crucial to prevent major damage. Likewise, it’s essential to know what type of substance will pass through the pipeline (steam, liquid, or gas). For this reason, knowing whether the valve operation is manual or automatic is necessary to act accordingly.

If you contact us, the experts at Valfonta will be delighted to provide you with attentive and personalized service. Additionally, they will also address your concerns and explain in detail the operation of pressure reducing valves. You just need to call us at 93 3720888 or email us at, and we will get back to you as soon as possible.

Advantages of the pressure reducing valves

  • They allow fully control over the pressure that gets in and out.

  • Eliminate the risk of overpressure in the distribution system.

  • Reduce the consumption of water.

  • Minimize the installation noises.

  • Maintain the outgoing pressure constant despite the incoming fluctuations.

  • Compact and economical.
