To ensure that we provide the highest quality product possible, FluoroSeal Inc. conducts a 100% radiographic inspection of each valve body per the requirements of ASTM E446 (DIN EN 444 & DIN EN462). In addition, each machined valve body is subjected to a 450 psig helium gas shell test prior to assembly. After assembly, HF Alkylation valves receive a 1.5 times max cold working pressure kerosene shell test per ASME B16.34 (DIN EN 12266-1), a low pressure gas seat test, and high pressure kerosene seat test.
