Ball valves tend to be more reliable due to their ease of automating only a rotary motion, unlike the wedgeplug type valve which must lift, rotate, then reseat. Reliability problems tend to ocurr in this area. Metso Automation and Velan both offer isolation and switch ball valves. Just don’t lose steam pressure!
