Safety & Relief Valves
Overpressure protection for vessels and lines
Safety & Relief Valves
Overview
Safety and relief valves safeguard pressure vessels, boilers and pipelines by automatically relieving excess pressure. Spring-loaded designs open at a set pressure to protect equipment and personnel, then reseat once safe conditions return.
Key Features
- Automatic set-pressure relief
- Pop-action for gas / vapour, modulating for liquid
- Conventional and balanced-bellows designs
- Tight reseating after relief
- Test certificate with set-pressure record
Applications
Boilers Pressure vessels Steam systems Oil & gas Chemical
