Safety & Control Valves
Pressure Release Valve
Pressure Release Valve is a self-operating safety valve designed to automatically release excess pressure from pipelines and pressure vessels when the system pressure exceeds a predetermined set point. The valve protects pumps, pipelines, tanks, and other equipment from damage caused by overpressure conditions while maintaining safe and reliable system operation.
Key Features
- Automatically releases excess pressure when preset pressure is exceeded.
- Protects pipelines, pumps, vessels, and equipment from overpressure damage.
- Spring-loaded mechanism ensures accurate pressure control.
- Fast opening and reseating action for enhanced safety.
- Reduces risk of pipeline bursts and system failures.
- Suitable for water, air, steam, and industrial fluid applications.
- Corrosion-resistant construction for long service life.
- Available in multiple pressure ratings and material combinations.
- Simple installation and low maintenance requirements.
- Optional manual lifting lever for periodic testing and inspection.
