Our product portfolio includes a wide range of safety valves, such as spring-loaded, pilot-operated, and lined valves, among others.
A safety valve, also known as a pressure relief valve (PRV) or safety relief valve, is a critical safety device installed on pressurized equipment such as pressure vessels, pipelines, boilers, and similar systems. Its primary function is to provide overpressure protection. When the internal pressure of the medium (e.g., gas, liquid, or steam) within the protected equipment exceeds a preset value, the valve automatically opens to discharge the excess medium, preventing further pressure buildup. Once the pressure drops below the preset value, the valve closes automatically, ensuring the system resumes safe and normal operation.
The preset pressure of a safety valve is typically set by an adjustable spring (spring-loaded design) or regulated by a pilot valve (pilot-operated design). These two primary categories are:
API Standard 521/ISO 23251 Section 4 outlines detailed guidelines for identifying overpressure scenarios. The most common causes include:
