Non-return valve with anti-pollution flange type EA453 DN80 149B3833

Non-return anti-pollution check valve – flanged – protection of the installation and safety of use

This flanged anti-pollution check valve of type EA453 is a reliable solution for protecting water installations against backflow and contamination. Its construction, based on proven materials and compliant with applicable standards, guarantees long-lasting and trouble-free operation. The valve finds application in both industrial installations and public buildings as well as single-family homes.

Construction and application

The EA453 valve is designed for mounting on pipelines with clean liquids and gases. Made of spheroidal graphite cast iron with a closing assembly of brass/bronze and PPO, it provides resistance to corrosion and mechanical damage. EPDM seals guarantee the tightness of connections. Flanges drilled PN10/16 facilitate mounting in existing installations. An additional advantage is the possibility of checking the tightness of the closure thanks to the inspection hole, which allows for quick identification of any problems without the need to disassemble the valve.

This valve is particularly useful in places where there is a risk of contaminated water flowing back into the source of drinking water, thereby protecting the health of users. The possibility of mounting in any position facilitates its installation even in hard-to-reach places.

Key features and benefits

• High reliability: The valve construction ensures excellent tightness and minimizes the risk of failure, which translates into long-term use without the need for frequent repairs.
• Versatility: The possibility of mounting in any position makes it easy to adapt the valve to different installation configurations.
• Easy maintenance: The inspection cover allows for current monitoring of the condition of internal elements without the need to disassemble the valve from the pipeline. Replacing the closing assembly is also simple and does not require specialized tools.
• Safety: Compliance with PN-EN 13959 and PED 97/23/CE directive guarantees safety of use and compliance with applicable regulations.
• Water drainage: The drain plug allows for easy emptying of the valve from water, which facilitates its maintenance and preparation for seasonal breaks in use.
• Low pressure drop: The valve design minimizes flow resistance, which translates into the efficiency of the entire installation.
• Access to control: Two control holes with ball valves allow you to check the tightness of the valve without disassembling it.

The flanged anti-pollution check valve type EA453 DN80 (catalog number 149B3833) is a solid and effective solution for professionals and demanding end-users who value safety, reliability and ease of use.
