High-Capacity Safety Valve

Pentair Valves & Controls’ newly introduced Crosby HCI ISOFLEX is a high-capacity safety valve to help power plant operators reduce lifecycle costs and minimize shutdown periods. The valve ensures cost-effective power plant operation with a unique full-nozzle, flanged design and adjustable lift option that reduces maintenance costs while maximizing plant efficiency. Specifically designed for 300 to 3,000 psig steam generators, the HCI ISOFLEX can withstand temperatures up to 1,100F/593C and is available in various inlet sizes, ranging from 1½ inch (38.1 mm) to 6 inches (15.24 cm). An extensive range of interchangeable spare parts enables operators to repair or exchange components individually, avoiding costly replacements and minimizing shutdown time.

The valve is also available with an optional restricted lift feature to eliminate overcapacity and ensure a more economic distribution of relieving capacity between the drum and superheater safety valves. This design not only reduces reaction forces for a greater lifespan but also allows for the use of smaller superheater safety valves in some operations, reducing overall installation costs. Additional benefits include precise blowdown control due to a two-ring design and exceptional seat tightness up to 95% of valve set pressure. (valves.pentair.com/valves)
