BRA.50.000 - flanged strainers for check valve F5

The BRA.50.000 flange sieve range is designed for integration with suction baskets in check valve systems. These sieves are mounted on PN 16 flanges in accordance with STN EN 1092-1 standards and feature a 5 mm hole size for effective particle filtration. They are commonly used in heating, plumbing, and pump systems to prevent debris from entering sensitive components.

Available in a range of nominal diameters from DN 50 to DN 250, each sieve is sized to match the corresponding flange connection and system requirements. The standard material is galvanized steel, though an optional stainless steel variant (AISI 316, type BRA.53.000) is available for more corrosive environments. Sieve lengths vary from 80 mm to 300 mm depending on DN size.

How to choose

• Select the correct DN size to match the flange connection of the suction basket and check valve.
• Ensure compatibility with PN 16 flanges as per STN EN 1092-1 specifications.
• Choose galvanized steel for standard applications or stainless steel (BRA.53.000) for environments with high corrosion risk.

Frequently asked questions

Can the sieve be replaced without removing the entire suction basket?
Yes, the BRA.50.000 is designed for easy removal and replacement via the flange connection, allowing maintenance without dismantling the full system.

What is the maximum particle size retained by the sieve?
The sieve has a 5 mm hole size, meaning it retains particles larger than 5 mm to prevent blockages downstream.
