Product catalog summary

Overview: The Ridart 442 Series Overfill Prevention Valves are designed to prevent overfilling of storage tanks by providing a positive shut-off during the loading process. These valves are compliant with several safety directives and standards, including ATEX 2014/34/EU and EN ISO 13616-1:2016.

Specifications: The valves are available in different models, each with specific materials and dimensions. For example, the 442-80 AL model features an aluminum body, PP HD + carbon floats, and a stainless steel poppet, with a 3" diameter and vertical installation. The weight varies by model, with the 442-80 AL weighing 2.80 kg.

Installation and Operation: The valves are designed for both vertical and horizontal installations, depending on the model. They operate by closing automatically when the tank reaches 90% capacity, ensuring no residual liquid remains in the pipe. This design facilitates easier and quicker installation without dismantling the manhole, reducing fire and fuel leak risks.

Certifications and Applications: The valves are ISO 13616:2016 certified and suitable for ATEX zones 0, 1, and 2, making them ideal for petrochemical applications. They are factory tested for long service life, withstanding up to 1500 closings as per European Norm specifications.
