The Miselli Pressurized Filling Plug Series FSB-P5 uses an advanced dual-valve system designed to maintain constant pressure inside hydraulic tanks<\/span><\/span>. <\/span>During the fluid extraction phase, the liquid level inside the tank decreases; at this point, the intake valve precisely regulates the airflow directed into the system<\/span><\/span>. <\/span>Conversely, when fluid enters the tank, the liquid level rises, generating natural internal overpressure<\/span><\/span>. <\/span>This excess pressure is safely managed and regulated outward by the discharge valve, which has an opening calibration strictly set at 0.35 Bar<\/span><\/span>.<\/span><\/p>\n

Advantages of the Regulated Pressurization System<\/h3>\n

The mechanism integrated into this component drastically reduces the volumes of air entering the tank during normal operating cycles<\/span><\/span>. <\/span>This significant reduction in airflow consequently limits the intake of impurities and contaminants from the external environment<\/span><\/span>. <\/span>Maintaining a significantly cleaner internal liquid ensures the correct and long-lasting operation of the entire associated hydraulic system<\/span><\/span>. <\/span>Furthermore, strict control of internal pressure systematically prevents structural deformation of the tank walls, preserving system integrity over time<\/span><\/span>.<\/span><\/p>\n

Construction Features and Materials<\/h3>\n

The Miselli Pressurized Filling Plug Series FSB-P5 features a robust structure and materials specifically selected to withstand the stresses typical of the hydraulic sector<\/span><\/span>. <\/span>The upper part consists of a durable chrome-plated steel cover, combined with a bottom plate featuring six venting sections<\/span><\/span>. <\/span>Air filtration is entrusted to a polyurethane element with a filtration rating of 40 \u03bc<\/span><\/span>. <\/span>Hydraulic sealing is ensured by a complete set of NBR gaskets: a flat sealing gasket with a thickness of 2.6 mm, an internal gasket measuring 24x30x5 mm, and specific flange gaskets with an external diameter of 84 mm and a thickness of 1.8 mm<\/span><\/span>. <\/span>The system includes a galvanized basket, galvanized chain, and practical galvanized bayonet connection to facilitate fluid inspection and filling operations<\/span><\/span>. <\/span>Mounting is carried out using a drilled flange, and the part is supplied complete with six galvanized M5 fixing screws and the rubber gasket required for installation<\/span><\/span>.<\/span><\/p>\n

Applications, Flow Rate and Fluid Specifications<\/h3>\n

Use of this component is strongly recommended in particularly dusty operating environments or in mobile applications<\/span><\/span>. <\/span>In these specific contexts, the presence of the pressurized breather valve very significantly reduces the risk of accidental oil leaks, increasing overall machine safety during movement<\/span><\/span>. <\/span>In terms of performance, the system supports a high air flow rate, reaching values up to 750 Lt\/min to meet intensive industrial requirements<\/span><\/span>. <\/span>Regarding chemical and operational compatibility with fluids, the manufacturer\u2019s technical specifications clearly indicate that use of the device in contact with water is not recommended<\/span><\/span>.<\/span><\/p>\n
