Pressurized Filling Plug Miselli Series FSB-P5
The Miselli Pressurized Filling Plug Series FSB-P5 in chrome-plated steel integrates a filtering basket and a dual-valve system calibrated at 0.35 Bar. This component regulates the pressure of the hydraulic tank, limiting the ingress of external impurities and preventing structural deformation. It guarantees an air flow rate of up to 750 Lt/min and, thanks to the galvanized bayonet connection, is ideal for mobile applications and dusty environments, ensuring constant protection against accidental fluid leaks.
The Miselli Pressurized Filling Plug Series FSB-P5 uses an advanced dual-valve system designed to maintain constant pressure inside hydraulic tanks. 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. Conversely, when fluid enters the tank, the liquid level rises, generating natural internal overpressure. This excess pressure is safely managed and regulated outward by the discharge valve, which has an opening calibration strictly set at 0.35 Bar.
The mechanism integrated into this component drastically reduces the volumes of air entering the tank during normal operating cycles. This significant reduction in airflow consequently limits the intake of impurities and contaminants from the external environment. Maintaining a significantly cleaner internal liquid ensures the correct and long-lasting operation of the entire associated hydraulic system. Furthermore, strict control of internal pressure systematically prevents structural deformation of the tank walls, preserving system integrity over time.
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. The upper part consists of a durable chrome-plated steel cover, combined with a bottom plate featuring six venting sections. Air filtration is entrusted to a polyurethane element with a filtration rating of 40 μ. 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. The system includes a galvanized basket, galvanized chain, and practical galvanized bayonet connection to facilitate fluid inspection and filling operations. 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.
Use of this component is strongly recommended in particularly dusty operating environments or in mobile applications. 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. In terms of performance, the system supports a high air flow rate, reaching values up to 750 Lt/min to meet intensive industrial requirements. Regarding chemical and operational compatibility with fluids, the manufacturer’s technical specifications clearly indicate that use of the device in contact with water is not recommended.
