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

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.

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.

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.

Your purifiers work best when filters are fresh. Replace them every six months, or sign up for auto-refills to get them shipped to your door, right when you need them.

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.

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.

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.

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.

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.

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.

Valfonta has been a beneficiary of the European Regional Development Fund, whose objective is to improve the use and quality of information and communication technologies and access to them. Thanks to this, they have been able to implement a production and plant control system (MES system). This action took place during 2022. For this purpose, they have received the support of the Industry 4.0 program of the Barcelona Chamber of Commerce.

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.

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

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 valfonta@valfonta.com, and we will get back to you as soon as possible.

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

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.
