Types of safety valves and how to choose the right one Safety valves 25/04/2025

Safety valves are essential components in many industrial systems. Their main function is to protect equipment and people from overpressure or system failures, releasing excess pressure when established limits are exceeded. However, not all safety valves are the same, and choosing the most appropriate one depends on various technical and operational factors.
In this post, they explain the main types of safety valves and offer key recommendations for selecting the most appropriate option in each case. They also highlight the importance of valve maintenance in Teiß, a fundamental aspect to ensure their proper functioning over time.
Main Types of Safety Valves
The following are the types of safety valves most commonly used in industrial settings:
- Spring Valves
These are the most common. They operate using a calibrated spring that is compressed by pressure. When the limit is exceeded, the spring is released, allowing the excess pressure to escape. They are used in boilers, compressors, pressure vessels, and other closed systems.
- Pilot-operated valves
These valves are actuated by a control pilot. They are more sensitive and precise, ideal for complex systems where more precise regulation of the opening pressure is required.
- Disc or burst valves
They operate with a calibrated disc that breaks when a certain pressure is reached. Although they are not reusable, they offer an instantaneous response and are used as secondary protection.
- Relief Valves
Although they are often confused with safety valves, their key difference is that they open gradually rather than abruptly. They are used in systems where constant pressure must be maintained.
How to Choose the Right Safety Valve?
To choose the right safety valve, it is essential to consider the following aspects:
- Opening and closing pressure: Must be adapted to the system's operating ranges.
- Fluid type: Not all valves are suitable for liquids, gases, or steam.
- Operating temperature: Materials and seals must withstand the thermal conditions of the environment.
- Applicable regulations: Comply with current industrial and safety standards.
- Activation frequency: In systems with frequent activation, it is advisable to opt for more durable or easy-to-maintain valves.
In addition, it is advisable to perform a valve inspection and adjustment in Teià periodically to ensure their reliability. These tasks must be carried out by specialized professionals who can verify the calibration and general condition of the mechanism.
Maintenance and repair: the key to a long service life
The correct choice of valve is only the first step. To keep it functioning optimally, it is essential to perform periodic maintenance. In this regard, they offer valve maintenance services in Teià, as well as as valve replacement parts in Barcelona, both original and compatible, ensuring a complete and quality service.
It's also important not to forget the auxiliary components. In many cases, failures are due to defects in the actuators. Therefore, they also perform valve actuator repair in Barcelona, guaranteeing a quick and accurate response to any technical incident.
Conclusion
Safety valves are an essential element for the protection of industrial equipment. Choosing the right one and performing professional maintenance guarantees not only the efficiency of the system, but also the safety of the facilities and personnel.
Having a technical team specialized in the inspection and adjustment of valves in Teià, as well as in the replacement of valve parts in Barcelona, is an investment that prevents unwanted downtime and prolongs the useful life of the system. And if the problem is in the actuators, the solution is also available. In expert hands: Valve actuator repair in Barcelona, with a guarantee and speed.
