Controls gravity flow discharge

Orifice slide gates are used to control gravity flow discharge from storage bins and hoppers. In the open position, the gate’s blade is completely removed from the control opening, making a resistance-free passage for the material stream. Orifice gates are also well-suited for controlling the material lines in vacuum and pressure, dilute-phase conveying applications.
