Goggle Style Gates

Plattco invented the goggle series valve in the 1980s to provide a solution for the discharge of a dry scrubber for the waste-to-energy industry.  These valves have been used extensively in waste to energy as well as coal fired power generation.  The valve is especially suited to handle the inevitable upset condition in the scrubber where the material discharging the scrubber is wet and sticky.  The seal cleaning action of the valve will pass the wet material and keep on running.

Companies around the world choose Plattco maintenance gates because they will:

• Effectively and reliably close and seal against material
• Perform in critical, demanding conditions
• Offer Convenient & Inexpensive Maintenance for decades of like-new operation

Operating Parameters:

• Maximum temperature capability is 500F/260F
• Maximum pressure capability of 2 PSI/.34 BAR
• Handles dry powder materials with the capability to handle wet material upset conditions

Excellence in Design:

• Cast valve housing made from cast gray iron
• Standard and custom sizes available, ability to match any flanges and transition to equipment above/below
• Internal sliding gate is made from 304ss for corrosion resistance
