Backflow preventer check valve PURE class EA 3/4 inch 1901050

Backflow prevention valve – protection of the installation and safety of use

The PURE EA class backflow prevention valve is a reliable protection for water supply systems against backflow. It is a key element, especially in places where protection of drinking water against contamination is required. Made of brass (CuZn40Pb2 – CW617N), it ensures durability and corrosion resistance. Designed for direct installation behind the water meter, it effectively protects against potential contamination.

Construction and application

This valve is used in water supply installations where protection against backflow is necessary. Its construction based on the principle of a check valve with a mesh filter (strainer) allows to stop mechanical impurities and prevents the flow of liquid in an undesirable direction. The maximum working pressure is 1 MPa (10 bar), and the maximum operating temperature is +65°C. The nominal diameter DN20 (3/4 inch) makes the valve compatible with most standard installations. The connection length is 75 mm.

Key features and benefits

• Backflow protection: Protects the water supply system against backflow, which is particularly important in the event of a network failure or pressure drop.
• Contamination filtration: The built-in mesh filter (strainer) stops mechanical impurities, protecting devices connected to the installation.
• Durability and resistance: Made of high-quality brass (CuZn40Pb2 – CW617N), which guarantees long-term use and corrosion resistance.
• Easy installation: Designed for horizontal mounting, which facilitates its installation in existing water supply systems.
• Compliance with standards: EA class ensures compliance with applicable standards regarding the protection of drinking water.
• Wide application: Ideal for use in residential, commercial and industrial buildings where protection of the water supply system is required.
• Net weight: Low weight of 0.177 kg facilitates transport and installation of the valve.

The PURE backflow prevention valve is an investment in the safety and reliability of your water supply system. It provides peace of mind, protecting against potential problems related to water contamination and equipment damage.
