What can we offer you from Valfonta?
At Valfonta, we are dedicated to the manufacturing and development of mechanisms for pressure control, ensuring greater effectiveness and efficiency in distribution systems and installations where fluids of different characteristics circulate.
We have specialized in the design, manufacturing, and customization of pressure reducing valves and pressure relief valves. Our ability to provide tailored solutions is based on a deep understanding of the varied and sometimes complex needs of different systems and installations.
The use of regulating valves is essential in the efficient and safe management of any fluid system. They not only control pressure but also prevent damage to pipelines and minimize fluid and gas losses and leaks. In this way, they contribute to operational efficiency, machinery safety, and environmental protection.

Distribution networks, especially in the industrial sector, are often complex and may have areas where the pressure is higher than what pipelines or equipment can safely withstand. This can happen for various reasons, such as proximity to pumping stations or being located in low elevation geographic areas where pressure can accumulate.
In these situations, pressure reducing valves become absolutely critical. They are capable of reducing the pressure within the system to a safe level, preventing the risk of pipe ruptures caused by excessive pressure. Additionally, they help prevent the leakage of any fluid or gas circulating through the system, safeguarding both the system’s integrity and the environment as a whole.
In summary, at Valfonta, we strive to produce the highest quality valves that provide precise and reliable pressure regulation, ensuring the efficiency and safety of your systems and installations.

What is the function of the pressure reducing valve?
This question can find its answer at the very core of the efficiency and safety of fluid systems. As a control valve, the pressure reducing valve plays a crucial role in adjusting the system’s output pressure. It does so consistently and reliably, unaffected by variations in input pressure or changes in the flow line demand.
At Valfonta, we specialize in manufacturing and designing this type of pressure regulating valves, with over fifty years of experience in the fluid systems industry. This long-standing expertise allows us to proudly state that pressure reducing valves are our specialty and passion.
The knowledge accumulated over more than half a century of service provides us with a solid and rich foundation to ensure that each of our customers receives the most suitable solution for their needs.
We don’t just make valves; At Valfonta, each project is a challenge that we approach with a personalized approach. We carefully analyze each installation, we consider all the needs and requests that our clients present to us, and we work meticulously to find the optimal solution and the most suitable valve.
Characteristics of the self-regulating excess pressure valves S1 and S2
In this post, we will showcase the features and differences between two of our most common pressure relief valve models, the S1 and S2 models. These are just two options from our extensive valve catalog. Feel free to request more information and personalized advice to help you choose the right valve for your specific needs.
Valve S1
It is a self-operated pressure relief valve. This series of control valves is suitable for vapor, compressed air, non-hazardous gases, and liquids. It has a very rapid response to demand. It features a single-seated globe valve. The stem is sealed by a double-layer bellows.
It is manufactured in stainless steel, and to prevent any damage to the bellows, the S1 series is equipped with an anti-rotation system. The diaphragm is reinforced with an intermediate lining. The regulation range is between 0.5 and 15 barg with different actuators. The valve opens when the upstream pressure increases. Maximum inlet pressure is 15 barg.
Other configurations:
Valve S2
Self-operated pressure relief valve. Its main function is to maintain the inlet pressure at an adjusted maximum value, relieving excess pressure downstream through the regulation axis.
When the inlet pressure increases beyond the set value, the valve opens proportionally to the detected pressure increase.
This model of S2 pressure regulators is suitable for low-temperature vapor (with condensation tank), compressed air, gases, and liquids.
The actuator is equipped with a high-quality reinforced membrane with an intermediate fabric layer. Its regulation range for the inlet pressure varies from 0.02 to 10 barg, depending on the different sizes of actuators.
The condensation tank is available and necessary when the fluid is vapor or for liquids with a temperature higher than 125º C to protect the membrane from overheating.
It is important to mention that the pressure relief valve is not a safety valve, and when necessary, an overpressure protection should be installed.
The applications of this type of valve are that it allows an area with excess pressure to feed another area with lower pressure, without leaving the main line undersupplied. In case of excessive consumption, it prevents overpressures.
As we can see, pressure valves are designed to reduce and stabilize the fluid pressure. They are primarily conceived as a pressure compensation system that aims to minimize variations in the output pressure.
The benefits of these self-regulating pressure valves are related to stabilizing pressure in all types of systems, preventing high pressures from causing cracks, vibrations, and noise in the pipeline, and avoiding pressure fluctuations at different times of the day.
Properly chosen and maintained control valves increase efficiency, safety, and profitability.
