Top Entry Ball Valves - E60T
These types of valves are being used for Natural Gas and Crude Oil Pipelines, NG Pipeline Pig Stations, Compressor and Measuring Stations, RMS Pressure Regulating and Measuring Stations for above & underground applications. Generally used between -46°C up to 100°C. PSL2 level can be obtained upon request and it can be manufactured with various materials.
SIL 2 & 3 certified. When required it can be manufactured from special material according to NACE corrosion standards and/or temperature class.
Top Entry Ball Valves are mainly used in pipelines. It is directly connected to the pipeline by welding. Although the general features are same with Full Welded or Split Body Ball Valves, the biggest difference is that the ball can get in or get out from the top of the valve which makes it possible to carry out maintenance, repair and to replace spare parts without removing the valve from pipeline. Other features are similar with Full Welded and Split Body Ball Valves.
