BRA.06.430, BRA.M6.430 PR - check valves - horizontal
This category includes horizontal inter-flange check valves from the BRA.06.430 and BRA.M6.430 PR series. These valves are designed for use in heating, ventilation, and air conditioning (HVAC) systems, water distribution, compressed air, oil, and hydrocarbon applications. They operate within a temperature range of -20°C to +100°C and are suitable for water with up to 50% glycol content. The valves are constructed from carbon steel (A216 WCB) for the body and disc, with NBR sealing and AISI 302 spring material where applicable. They are not suitable for steam applications.
Available in nominal sizes from DN 50 to DN 350, these valves are designed for installation between flanges with PN 6 (up to DN 250), PN 10, or PN 16 according to EN 1092. They feature a minimum back-pressure requirement of 0.3 bar for proper closure. Variants include both spring-loaded and non-spring models.
How to choose
- Select the appropriate DN size based on the nominal diameter of the system piping.
- Ensure compatibility with flange standards (PN 6, PN 10, or PN 16) and flange spacing (L values vary by DN).
- Choose between spring-loaded (series M6) or non-spring (series 06) variants depending on the required flow characteristics and system pressure conditions.
- Verify that the operating temperature and media (e.g., water with glycol) are within the specified limits.
Frequently asked questions
Can these valves be used in steam systems?
No, these check valves are not suitable for steam applications due to material and design limitations.
What is the maximum operating pressure for different DN sizes?
Maximum pressure is 25 bar for DN 32 to DN 200, and 12 bar for DN 250 to DN 300.
