442S Overfill Prevention valve

Product catalog summary

Overview: The Overfill Prevention Valve Ridart is designed to prevent overfilling during the transfer of hazardous or dangerous fluids. It is applicable in industries such as petrochemical and pharmaceutical. The valve operates automatically, ensuring no residual liquid remains in the pipe after loading, and requires the operator to remain present during refueling.

Compliance and Safety: This safety device complies with several directives and standards, including ATEX 2014/34/EU, EN ISO 13616-1:2016, and EN ISO 80079-36:2016. It is also in accordance with specific technical norms and amendments.

Specifications: The valve features a maximum operational pressure of 8 bar for pressure filling and requires operator supervision during the loading process. It supports both gravity and pumped filling, as well as remote or direct filling, with no risk of fire or fuel leakage. Installation is straightforward with drop and riser pipes available upon request.

Technical Details: The valve is identified by product code 442S and is designed for vertical installation with 3”F BSPP threads. It has an initial closure level of 160 mm and a final closure level of 110 mm. The minimum flow rate is 60 l/min at 230 mbar, and the maximum flow rate is 900 l/min at 8 bar. The body is made of aluminum, with stainless steel screws, poppet, and support, PTFE + carbon seals, and a PE HD + aluminum sputtering float.

Maintenance: Regular checks are necessary to remove dirt and ensure proper storage and handling to prevent particle entry or dust deposition. Maintenance should be performed by specialized staff using appropriate tools, and any tampering voids the warranty and safety protection. The protection system is unidirectional and suitable only for horizontal installation.

Installation and Compliance: Before installation, ensure the valve model complies with local and national laws regarding tank capacity requirements, typically 90%. Proper training and management of forecourt workers are essential to prevent product spillage and environmental contamination.
