These valves have been used in a wide range of applications, from high-temperature, high-pressure applications to ultra-low-temperature applications, and have a proven track record of use in a wide variety of elds. These valves always demonstrate well-balanced actuation performance (popping/closing), which is the most important performance of safety valves, under all operating conditions. Moreover, the discharge capacity is guaranteed by the National Board of Boiler and Pressure Vessel Inspectors (U.S.) based on ASME BPVC (SEC. I/SEC. XIII), so you can use these valves with con dence. 11 NAKAKITA FCV PRODUCT CATALOG
