Resilient Seated Gate Valves
During the 1980’s, the waterworks industry was introduced to the resilient seated gate valve and Kennedy Valve Company was at the forefront of this industry wide movement. Today we offer both our KS FW AWWA C509 Full Wall and KS RW AWWA C515 Reduced Wall resilient seated gate valves, embodying the latest valve technology for simplicity, durability, and superior performance.

Rotating Disc Gate Valves
Kennedy Rotating Disc gate valves have been used successfully since 1908. The innovative rotating seating surface self-cleans and seats in a different location with each operation. Through the moving seating surface action, the sealing components wear more evenly; remaining consistent, smooth and properly fitting for much longer. As a result, the valve has less chance of fouling, leakage or failure and lasts dramaically longer.
