Mounted horizontally, the machined square-edged blade mechanically clears the material from the sealing surfaces on each closing cycle allowing it to discharge beneath the valve. The square blade and seal design eliminates the open cavities where material collects in traditional gate valves.

The most notable improvement made to the Vortex Clear Action Gate, is the ability to seal the valve’s body. This added feature is essential to prevent material leakage into the atmosphere. In addition, the slide gate’s air purge was updated to greater reduce material migration from material flow to valve body.
