Askalon represents Emerson’s pressure relief portfolio which provides a complete range of standard and customized solutions, whatever demand you have for pressure protection, primarily from brands like Sempell™™, Varec™, Crosby™ and Anderson Greenwood™. Emerson has the most comprehensive range of pressure relief devices, designed for applications from gas to steam, liquid and mixed phases, from cryogenic temperatures to super-critical boilers.
We have a complete range of spring-loaded pressure relief valves from general pressure protection to extreme conditions. Designed, certified and tested in accordance to most codes and standards around the world. With metal or soft seats, threaded, flanged, welded or hub connections, the largest range of pressure relief valves builds on many decades of experience. With the broadest range of pilot operated pressure relief valves, we are able to solve the most demanding pressure protection challenges, providing reliable protection at low operating costs. The configurations and options available provide the perfect match for any application that requires highly reliable protection and flexibility.
Our low pressure relief valves are designed for extremely accurate low pressure protection with configuration flexibility for ease of maintenance and enhanced reliability. The soft seats are specially designed to provide extreme tightness even under the lowest pressures. These valves feature very large capacities for the most economical configuration.
Protecting steam processes against over-pressure has always been one of the most challenging duties for engineers. Spring loaded, pilot operated or power assisted, from low pressure steam to super-critical boilers, each safety valve is supported with some of the largest steam testing facilities in the world.
