Kennedy Swing Check Valves
A.W.W.A. C508 was developed in 1976 to set a standard for the manufacture, testing and application of Iron Body
Bronze Mounted (IBBM) Check Valves. The valves are designed with an iron body and include either metal-tometal or composition-to-metal seating.
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. For restricted
spacing requirements Kennedy Valve manufactures a Wafer Check Valve that also helps to control water hammer.
Features
Swing Check Valve-AWWA
• Stainless steel hinge pin.
• Working parts are removable through the top of the valve.
• Tapped bosses available.
• Available with lever-and-spring or lever-and-weight.
• Double bronze side plug construction.
• Bodies are made of high strength cast iron with reinforced
flanges ‑ ANSI B 16.1/125 # flanges.
• May be installed in a vertical line with the flow up.

Kennedy Check Valves
It is generally recommended, that when using Kennedy swing
check valves, that you locate the valve at least 5 to 10 pipe diameters down stream from any flow disturbance or obstruction
(valve, pump, elbow, reducer, etc.). Turbulence close to the check
valve may result in valve "chatter" resulting in premature failure
of the check valve.
As stated in AWWA C508, "Conditions of water hammer, hydraulic
pulsation, and excessive operating noise are results of system
design rather than valve design and are beyond the scope of this
standard and require special design and construction considerations."

Kennedy Iron Swing Check Valves UL/FM
Underwriters’/Factory Mutual
Underwriters’ Canada
Kennedy Swing Check Valves are for use where backflow is to be prevented. The disc is designed with ample
tolerances to compensate for seat ring wear. The spinning action of the disc creates a regrinding effect that cleans
the seat ring of foreign particles. The disc is also self-adjusting. All moving parts of these valves are bronze to
bronze, minimizing wear and corrosion problems.
These valves are listed by Underwriters’ Laboratories and approved by Factory Mutual Fire Research Corp. and
have body markings “UL” and “ FM ” signifying the listing and approval.

The Kennedy Figure 426 R Grooved Check Valve may also be used as a Riser Check Valve. This valve would be
a lightweight substitute for an “Alarm Valve Assembly”. The valve is intended to be installed vertically in a sprinkler
riser, with appropriate trim (optional purchase). Each valve is tapped 1/4" NST both above and below the clapper for
pressure gauges, and 11/4" or 11/2" NSP (depending on valve size) for the drain outlet.

Cushion Check (Must specify vertical or horizontal installation when ordering)
If possible, it is preferable to eliminate water hammer. The best way to eliminate water hammer is in the design
of the piping system. For most cases where water hammer exists it is preferable to reduce its effects by causing
the check valve to close so quickly that the flow is not able to reverse. Kennedy Valve makes a Figure 706 Wafer
Check Valve that is intended as an anti-water hammer valve. Kennedy Valve also has available lever and weight
and lever and spring arrangements on the Figure 1106 Check Valve.
In some cases the customer may want an arrangement that retards the closing of the check valve. The customer
may want such an arrangement for those cases where the water column actually has an opportunity to reverse or
even separate, such as might occur when the check valve is not at the lowest elevation in the system.

For those customers, Kennedy Valve makes available the Figure 1206 Cushion Check Valve. The Figure 1206
Cushion Check Valve is a Figure 1106, AWWA valve with a lever and weight and a pneumatic cylinder arrangement. The pneumatic cylinder has a needle valve that allows the customer to adjust the time required for the valve
to close.
The Figure 1206 Check Valve may be ordered from the factory either as flow horizontal or flow up. The cylinder
arrangement is available mounted on either side unless specified the Figure 1206 valve will be supplied with the
cylinder on the right side (when facing the inlet) and for horizontal flow.
The Figure 1206 has internal components identical to the Figure 1106 except that the hinge pin is made from heat
treated, type 431 stainless steel and is unique to the Figure 1206.
