What is the function of this pressure relief valve?

Pressure relief valves, also known as overpressure valves, play a fundamental role in pressure management in industrial systems and pipelines. Their main purpose is to release accumulated pressure when a fluid exceeds a pre-established level. These valves play a crucial role in ensuring that the pressure in a system is maintained within safe and operational limits.

The importance of pressure relief valves lies in their ability to prevent overpressure in systems, which could result in costly or even dangerous damage. In addition, they help protect equipment and pipes from potential failures due to excess pressure, which helps maintain the integrity and efficiency of industrial facilities.

At Valfonta, we have a solid track record in the manufacture and distribution of pressure relief valves. Our experience translates into guaranteeing solutions adapted to various installations. We carefully study each system and consider all the specific needs and requirements of our clients to provide the optimal valve that ensures safe and effective operation of your installation.

Types of valves you will
find in our catalog

  • Pressure relief valves (spring-loaded model – S3): the relief valve serves to relieve the upstream adjustment pressure by controlling the set pressure. This model is suitable for use in steam, gas (group 1 and 2) and liquid applications.

  • Excess pressure valve (models PRV53 /PRV54): these are valves that open and expel excess pressure when it exceeds the set value. This model is suitable for use in liquid, gas or steam applications. They are manufactured in AISI 316L stainless steel.

  • Excess pressure valve (model PRV55): this is a valve with the same function as the previous ones, but the regulation is carried out by a membrane. Designed for use in a long list of applications such as chemical laboratories, sanitary plants, compressed air, sprinkler systems, steam plants, distilleries, dry cleaners…

  • Excess pressure valve (model S1): very suitable for steam, compressed air, gases and non-hazardous liquids. It offers a very fast response. Its regulation range is between 0.5 and 15 barg scaled in various actuators.

  • Excess pressure valve (model S2): this model is usually used to maintain the inlet pressure of the valve at its set point. When it rises above the point, the valve opens proportionally to the pressure. This series of regulators is suitable for compressed air, gases and non-hazardous liquids. For steam we recommend the S1 model.

What are the benefits of using pressure relief valves in terms of safety and equipment maintenance?

One of the main functions of pressure relief valves is to prevent the accumulation of excessive pressure in systems and equipment. This is essential to avoid potential damage or catastrophic failures that could occur if the pressure exceeds safe limits. By releasing excess pressure in a controlled manner, these valves maintain the integrity of the equipment and the safety of the work environment.

The use of pressure relief valves contributes to increasing the lifespan of equipment by reducing exposure to overpressure situations. This minimizes premature wear and the need for costly repairs. In addition, by preventing equipment from constantly operating under high pressures, efficiency is improved and energy consumption is reduced.

Personnel safety is a priority in any industrial environment. Pressure relief valves play a fundamental role in ensuring that working conditions are safe. By releasing pressure in a controlled manner in emergency situations, they help prevent serious accidents and protect the physical integrity of workers.

Complying with regulations is essential in the industry. The use of appropriate pressure relief valves ensures compliance with safety and environmental standards, which avoids legal penalties and guarantees the ethical and responsible operation of the facilities.

The monitoring and maintenance of pressure relief valves are easily integrated into predictive maintenance programs. This allows identifying potential problems before they become critical situations, reducing unplanned downtime and associated costs.
