FAQ
What types of containers are suitable for the EBRO BE250/BE300 container valve?
The BE250/BE300 is designed for bottom shut-off applications and is suitable for conical hoppers. The connecting flange must match the container connection standard, and the flange facing can be configured for EN 1092 Form A/B, ASME RF or FF.
What are the nominal diameter, pressure and temperature ranges of the BE250/BE300?
The series is available with nominal diameters of DN 250 and DN 300, with a maximum operating pressure of 1 bar. The operating temperature range is -20°C to +160°C, but the permissible temperature must be confirmed together with the operating pressure and medium conditions.
What manual operating options are available for the BE250/BE300?
This container valve is designed for manual operation and can be configured with an interlock, inclined handle, or open/close handle. The appropriate manual operating option should be selected based on the installation space at the container bottom, accessibility and site operating requirements.
Which standards does the BE250/BE300 meet for sealing performance?
The valve meets the Leakage Rate A requirement of EN 12266 and complies with ISO 5208 Category 3. EPDM, NBR, FPM or SBR-green sealing materials are available and should be selected according to the medium and temperature conditions.
What are the main materials used in the BE250/BE300, and what are its maintenance characteristics?
The valve body is made of GD-AlSi9Cu3 aluminum alloy (3.2163), while the disc is made of G-X6CrNiMo18-10 stainless steel (1.4408) or X2CrNiMo17-12-2 stainless steel (1.4404). The valve uses a multiple shaft bushing design, is maintenance-free, and can be disassembled for material recycling.
