Pilot-Operated Safety Valve for Oil and Gas Applications

The new pilot-operated safety valve is available as both pop-action valves and modulate-action valves. The typical application areas of the pilot-operated safety valve (POSV) are refineries and gas processing plants, compressors in gas pipeline systems and offshore applications. The own-media-controlled POSV offers the advantage that the plant can be run close to the set pressure of the valve. This leads to an increase in the capacity utilization and consequently of the efficiency of the plant. By means of the harmonized standard DIN EN ISO 4126-4 pilot-operated safety valves are now also approved in Europe. For decades already their technology has been proven in the American market and in the Middle East. The valve will be with a short four-week lead time ex works in Germany. As a special design feature, the tubing between the pilot valve and the main valve is integrated in the main valve cover, reducing the risk of damage or freezing. The backflow preventer is included as standard.
