Kennedy Swing Check Valves are designed and manufactured in conformance with A.W.W.A. C508 and are for use on water, oil and gas lines. Under certain circumstances where it is desirable to have more positive control of the closing of the disc, the valves can be supplied with either lever-and-spring or lever-and-weight.
Increasing Check Valve – Series 1306

Cushion Check Valve – Series 1206 / Oil Cushion Check Valve – Series 1606
The cushion check valve is available for customers needing an arrangement that retards the closing of a check valve, potentially due to the water column having the opportunity to reverse or even separate due to not being at the lowest elevation of the system. The pneumatic cylinder has a needle valve that allows the customer to adjust the time required for the valve to close.
