Application scenarios
Continuous Discharge and Metered Feeding of Powdered and Granular Bulk Materials
For the continuous discharge, flow control, and metered feeding of non-liquid, non-gaseous bulk materials such as powders and granules. The product supports safe and consistent conveying of free-flowing materials and can reduce stratification, compaction, and wear during conveying.
Controlled Discharge of High-Temperature Bulk Solids
For the controlled discharge and feeding of bulk solids such as powders and granules. The standard operating temperature range is -20 °C to +100 °C, with an optional range up to +250 °C. The specific configuration and operating temperature conditions must be confirmed for the actual application.
Selection points
Non-Fully Sealed Bulk Material Feeding Design
The body and rotor are not fully sealed, helping preserve material integrity. The product is explicitly not suitable for liquid or gaseous media.
Conveying Characteristics That Reduce Stratification and Compaction
Suitable for the safe and consistent conveying of free-flowing materials. It can significantly reduce stratification during conveying and prevent material compaction or wear during loading and conveying.
Maintenance-Free Triple-Bushing Design
The product features a maintenance-free design with a triple-bushing arrangement.
Flexible Installation Position and Direction of Rotation
The product can be installed in any position, supports clockwise or counterclockwise rotation, and allows speed control. The electric actuator speed range is 30 min⁻¹ to 100 min⁻¹.
Optional Rotor Surface Finish and Hardening
The product is equipped with a stainless steel rotor, with mirror polishing available as an option. A hardened rotary valve configuration is also available.
Defined Temperature Range and Flange Interface Options
The nominal size range is DN 150 to DN 500. Flange connections are available in EN 1092 PN 6/10/16 or ASME Class 150. The standard operating temperature range is -20 °C to +100 °C, with an optional range up to +250 °C.
FAQ
What media is the EBRO FS-M rotary feeder valve suitable for conveying?
The FS-M is designed for the continuous conveying, flow control, and metered feeding of solid materials such as powders and granules. It is not suitable for liquid or gaseous media. Its body and rotor are not fully sealed, with the design focused on preserving material integrity and reducing compaction, wear, and stratification during loading and conveying.
How should the FS-M rotary feeder valve's size, pressure, and temperature range be selected?
The FS-M is available with nominal sizes from DN 150 to DN 500 and a maximum working pressure of 6 bar. The standard operating temperature range is -20 °C to +100 °C, with an option for temperatures up to +250 °C. Selection should take into account the material particle size, required conveying capacity, system interface dimensions, actual pressure, and operating temperature conditions.
Which flange connection standards are supported by the FS-M?
The FS-M can be fitted with EN 1092 PN 6, PN 10, or PN 16 flange connections, or with an ASME Class 150 connection. Its face-to-face dimensions comply with the EBRO factory standard. For replacement installation or system integration, the equipment interface and face-to-face dimensions should both be checked.
How is the feeding rate adjusted on the FS-M?
The FS-M provides continuous feeding by using an electric actuator to drive the rotor. The actuator power supply is 230V or 400V, 50Hz or 60Hz, and the speed range is 30 min⁻¹ to 100 min⁻¹. Speed control can be selected to adjust the flow rate during conveying and metered feeding. The direction of rotation can be set to clockwise or counterclockwise.
What are the installation and maintenance features of the FS-M?
The FS-M can be installed in any position and features a triple-bushing arrangement with a maintenance-free design. For free-flowing materials, this configuration supports safer and more consistent conveying. A zero-position stop function is also available to provide sealing in the stopped position.
