The T205 Series tank blanketing regulator is a direct-operated and spring-loaded regulator.
The regulator prevents a stored liquid from vaporizing into the
atmosphere, reduces liquid combustibility, and prevents oxidation or
contamination of the product by reducing its exposure to air. The T205
Series maintains a slightly positive pressure and thereby reduces the
possibility of tank wall collapse during pump out operation. The T205
Series is available in two configurations: Type T205 for internal
pressure registration and Type T205M for external pressure registration.
