Product description

Orbinox BC is a fabricated square-port low-pressure knife gate valve used for bulk handling, silo discharge and highly solids-loaded media. It is intended for engineers and maintenance teams that need dependable isolation or flow control where the medium and operating conditions demand a purpose-built valve design.

BC uses a fabricated square or rectangular port for solids and bulk-material discharge, with metal-to-metal or EPDM seating and carbon-steel or AISI 316 body options. Its geometry is intended for low-pressure outlet and material-handling duties rather than conventional liquid throttling.

Standard fabricated sizes run from 150 x 150 to 600 x 600 mm at 1 bar working pressure, with other dimensions on request. Current data lists carbon steel operation from -10 to +80 °C and AISI 316 from -20 to +80 °C.

Matching the valve design to solids content, pressure direction and sealing duty helps reduce jamming, premature wear and unplanned shutdowns. AxFlow can support configuration review, actuator selection, spare parts and service throughout the valve lifecycle.


Orbinox BC is used for bulk handling, silo discharge and highly solids-loaded media. Its construction is selected for that specific process duty. AxFlow can help verify suitability for the medium and operating conditions.
Standard fabricated sizes run from 150 x 150 to 600 x 600 mm at 1 bar working pressure, with other dimensions on request. Pressure capability depends on size and configuration. The exact rating should be checked before ordering.
Actuation options depend on the exact Orbinox model and size. Manual, pneumatic, electric or hydraulic operation is available across the wider Orbinox range. AxFlow can help size the actuator for the actual duty.
Material selection should reflect the medium, solids content, abrasion, chemistry and temperature. Different Orbinox configurations use different body, gate and seat materials. The final material combination should be verified for the process.
AxFlow can help identify service parts for the exact valve configuration. Model, size, seat type, body material and actuator details are useful for correct identification. Contact AxFlow for availability and a quote.
