Kennedy Rotating Disc gate valves have been used successfully since 1908. Kennedy Rotating Disc gate valves clean themselves with every operation. Deposits are removed in travel, eliminating build up on the seating surfaces that could cause leakage. The rotating action of the discs creates a different seating position each time the valve is closed. Uneven or excessive wear is prevented, so the sealing components remain smooth and operational years longer without maintenance or replacement. These advantages, along with uncompromising quality control, ensure that Kennedy Valve rotating disc gate valves will be ideal for water and wastewater applications.
