What is a pressure reducing valve for steam?

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.

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.

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.

On the other hand, you will also find pressure regulating valves in our company:

• Piston-type pressure regulator valves (model PRV 20): this model is balanced using a piston that has been specifically designed to provide a much constant pressure.
• Self-powered pressure regulator valves (model M1): they are used to control the steam but also for compressed air, certain liquids and non-flammable non-toxic gas.
• Self-operated pressure regulating valves: are designed to handle low outlet pressure gases, liquids and certain gases.

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.
