442 Overfill Prevention valve

Product catalog summary

Overview
The Overfill Prevention Valve Ridart is designed to prevent overfilling during the charging 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 the loading process. Operators must 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 crucial for preventing fire hazards and ensuring safe operations.

Specifications
The valve is available in three models: Stainless Steel, PTFE coated, and Aluminium. Key specifications include:

Max operational pressure: 8 bar for pressure filling.
Vertical installation with 3”F BSPP threading.
Flow rates: Minimum 60 l/min at 230 mbar, Maximum 900 l/min at 8 bar.
Initial and final closure levels vary by model.

Chemical Suitability

Aluminium model: Suitable for traditional fuels without additives.
PTFE coated model: Suitable for special fuels and non-aggressive solvents.
Stainless Steel model: Suitable for aggressive solvents, acids, or bases.

Maintenance
Regular maintenance is necessary to ensure the device remains free of dirt and particles. Maintenance should be performed by specialized staff using appropriate tools, as per the general instruction manual. Tampering voids the warranty and safety protection.

Installation
The valve can be installed under the manhole lid of a tank without removing the manlid. It can be pre-assembled with an aluminum drop tube and/or riser pipe as per customer requirements. Installation must comply with local/national laws regarding tank capacity requirements.

Additional Features

Easy installation with drop and riser pipe available on request.
Supports gravity or pumped filling, remote or direct filling.
