442OR Horizontal 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 ATEX Directives 2014/34/EU, EN ISO 13616-1:2016, EN ISO 80079-36:2016, and other relevant technical norms and regulations. It is designed for horizontal installation and can handle a maximum operational pressure of 8 bar.

Specifications: The valve features a right and left 3”F BSPP thread, with a body height of 95 mm. The initial closure level is 170 mm, and the final closure level is 90 mm. It supports a minimum flow of 60 l/min at 230 mbar and a maximum flow of 900 l/min at 8 bar. The body is made of aluminum, with other components made of brass and stainless steel.

Installation and Maintenance: Proper installation requires adherence to directives and the user manual. Maintenance should be performed by specialized staff using appropriate tools, ensuring the device is free from dirt and particles. The protection system is unidirectional and suitable only for horizontal installation. Tampering voids the warranty and compromises safety.

Operational Guidelines: Operators must be trained to inspect loading adaptors and hoses to prevent spills and environmental contamination. The valve must comply with local laws regarding tank capacity, typically 90%.

Additional Information: For custom applications or maintenance inquiries, contact [email protected]. Declaration of Conformity and user manuals are available at www.ridart.it/support.
