Safety Valve
Safety Valve supplier In Africa providing reliable pressure relief valves for industrial overpressure protection.
Safety Valve supplier In Africa, African Valve provides automatic overpressure protection for pressure vessels, pipelines, boilers and process equipment. When system pressure reaches the predetermined set point, the valve lifts to release excess pressure and reseats once operating conditions return to the specified range. Their selection depends on the protected equipment, relief capacity, operating medium and applicable pressure-relief standards.
Safety Valve Features
- Spring-loaded or pilot-operated pressure relief mechanism
- Precisely adjustable set-pressure range
- Pop action or modulating lift characteristics
- Conventional and balanced-bellows configurations
- Open or closed bonnet arrangements
- Soft or metal seat options
- Blowdown adjustment for controlled reseating
- Suitable for gas, steam and liquid services
