Application scenarios
Check function and backflow prevention in piping systems
Installed in the pipeline circuit, the butterfly check valve maintains one-way media flow and prevents backflow, making it suitable for piping systems that require flow direction control and backflow protection.
Media conveyance in medium and low-pressure industrial pipelines
The valve is suitable for industrial piping systems with nominal sizes from DN 50 to DN 600 and connects to flanges complying with EN 1092 PN 10/16 or ASME Class 150, operating from 0°C to +130°C provided the pressure, media and temperature conditions are met.
Dismounting and material recycling applications
With its dismountable wafer-type design, the valve can be removed and its materials sorted for recycling during equipment dismantling or piping system modifications.
Selection points
Pressure ratings segmented by nominal size
The operating pressure is 16 bar for DN 50 to DN 250 and 10 bar for DN 300 to DN 600; when selecting a valve, verify the corresponding pressure limit against the actual nominal size.
Defined shut-off leakage class
The valve's leakage class complies with EN 12266 Leakage Rate A and ISO 5208 Category 3 and can be specified as the acceptance requirement for shut-off leakage.
Wafer-type flange connection compatibility
The wafer-type connection follows the EN 558-1 and ISO 5752 face-to-face standards, fits EN 1092 PN 10/16 and ASME Class 150 flanges and matches EN 1092 Form A/B and ASME RF/FF sealing faces.
Maintenance-free, dismountable and recyclable
The product is a maintenance-free wafer-type butterfly check valve that can be dismounted and whose materials can be recycled.
FAQ
Which pipe sizes and flange connection standards is the EBRO DC butterfly check valve suitable for?
The EBRO DC butterfly check valve covers nominal sizes from DN 50 to DN 600 and uses a wafer-type connection. It can be used with EN 1092 PN 10/16 or ASME Class 150 flanges; applicable flange sealing faces include EN 1092 Form A/B, ASME RF and FF.
How do I select the operating pressure rating of the DC butterfly check valve based on pipe size?
The DC butterfly check valve has an operating pressure of 16 bar for sizes up to DN 250 and 10 bar for DN 300 and above. When selecting a valve, match the pipeline nominal size against the system design pressure.
Which standards does the sealing performance of the DC butterfly check valve comply with?
