OUR PRESSURE RELIEF / EXCESS PRESSURE VALVE MODELS

What is the function of a pressure relief valve?

Pressure relief valves, also known as overpressure valves, play a fundamental role in managing pressure 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 remains within safe and operational limits.

The significance of pressure relief valves lies in their ability to prevent overpressure in systems, which could result in costly or even hazardous damage.

Additionally, they help protect equipment and pipelines from potential failures due to excess pressure, contributing to maintaining the integrity and efficiency of industrial facilities.

Cómo diseñar una válvula de presión

Our experience translates into the assurance of providing tailored solutions for various installations. We meticulously study each system, taking into account all the specific needs and requirements of our clients to supply the optimal valve that ensures safe and effective operation of their facility.

What types of pressure relief valves will you find in our catalogue?

  • Pressure relief valves (spring loaded model – S3): the relief valve serves to relieve the upstream pressure by controlling the set pressure. This model is suitable for use with steam, gas (groups 1 and 2) and liquids.  

  • 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 with liquids, gases or vapours. They are made of AISI 316L stainless steel.

  • Excess pressure valve (model PRV55): this is a valve with the same function as the previous ones, but in this case the regulation is carried out by a diaphragm. 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): well-suited to steam, compressed air, gases and non-hazardous liquids. It offers a very fast response. It has a regulation range of between 0.5 and 15 bar scaled in various actuators.

  • Excess pressure valve (Model S2): this model is typically used to maintain the valve inlet pressure at its set point. When it rises above this point, the valve opens proportionally to stabilise 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?

Pressure relief valves offer a series of significant benefits in terms of safety and equipment maintenance in industrial environments and systems operating with pressurized fluids:

  • Protection against overpressure: 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 ensure the safety of the working environment.

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

  • Accident prevention: 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 during emergency situations, they help prevent serious accidents and protect the physical integrity of workers.

  • Compliance with regulations: Adhering to industry standards and regulations is essential. The use of appropriate pressure relief valves ensures compliance with safety and environmental standards, preventing legal penalties and ensuring the ethical and responsible operation of facilities.

  • Predictive maintenance: Monitoring and maintaining pressure relief valves easily integrate into predictive maintenance programs. This allows the identification of potential issues before they become critical situations, reducing unplanned downtime and associated costs.
