Non-return valve with check function flanged type EA453 DN100 149B3834

Non-return anti-pollution check valve – flanged – reliable protection for your installation

This flanged anti-pollution check valve, type EA453, is a key element protecting the installation against backflow of the medium and potential contamination. It is a universal device used in both water supply systems and industrial applications where protection against liquid or gas backflow is required. The valve design allows for installation in any position, making it easy to install even in hard-to-reach places.

Construction and application

The EA453 valve is characterized by a solid construction made of ductile iron and brass/bronze and PPO (polyoxyphenylene) in the parts responsible for closing. EPDM gaskets ensure the tightness and durability of the connections. The flanges are drilled according to PN10/16 standards, guaranteeing compatibility with existing infrastructure. Thanks to the sealing control port, the valve allows for regular checking of its correct operation without the need for disassembly from the pipeline. Additionally, a special mounting system for the closing assembly allows for its quick replacement without the use of specialized tools.

This valve finds application in a wide range of installations where protection against medium contamination is required, e.g.:

• Potable water supply systems

• Heating installations

• Cooling systems

• Industrial processes using clean liquids and gases

Key features and benefits

• Versatility: The ability to mount in any position facilitates installation and adaptation to different conditions.

• High reliability: Solid construction with high-quality materials ensures long-lasting and trouble-free operation.

• Easy maintenance: The inspection cover allows for quick checking of the condition of internal elements without disassembling the valve. Replacing the closing assembly is simple and does not require specialized tools.

• Safety: Compliance with PN-EN 13959 standard guarantees compliance with strict safety standards.

• Low pressure drop: The valve design minimizes pressure losses of the flowing medium, which translates into energy efficiency of the system.

• Inspection ports: Two inspection ports with ball valves (DN1/2’’ or 1/4’’ depending on the diameter) allow for easy checking of tightness and performing installation tests. The drain plug allows for draining water from the valve.

• Temperature resistance: The valve can operate at temperatures from -10°C to +100°C, making it suitable for applications in various environmental conditions.

The flanged anti-pollution check valve type EA453 DN100 (catalog number 149B3834) is an investment in the safety and durability of your installation. Its solid construction, ease of installation and maintenance, and compliance with applicable standards make it an ideal choice for both professional installers and end users. The connection length is 300 mm.
