MATERIAL SPECIFICATIONS
FIG. 400G
Grooved-End Silent Check Valve
Available in Sizes 2" thru 10"
The 400G is a center guided, spring loaded,
silent check valve. Designed and engineered
for silent operation with low head loss, the
valve disc will close prior to the reversal of
fow, thereby preventing or minimizing water
hammer and damaging shock.
• The 400G can be used in any HVAC,
industrial or commercial grooved piping
systems.
• The valve is designed for liquid service
with any pipe orientation, fow up or
down.
• Bronze metal seats are standard, with
Stainless Steel or resilient seats available
as an option.
• Flow coeffcients for this valve are some
of the lowest in the industry and are
listed for each size on the drawing.
NOTE:
Valve is designed for liquid service only. Install 3 to 4 pipe
diameters downstream from pump discharge or elbows to
avoid fow turbulence.

Cv FLOW
* Flow coeffcient is the number of U.S. gallons/minute of 60° F (16° C) water that will fow through a valve with 1 psi
(0.069 bar) of pressure drop across the valve.
