is spring loaded normally closed. The center
guided disc is spring loaded. The once patented
feature that results in silent shut off, is
the relation of the disc to the seat when
in the open position. This distance is approximately
¼ of the valve size. It is the short
disc travel distance coupled with the spring
force that results in silent shut-off.
VALWORTH

utilizes for wide range of applications. Wafer
check valve approaches the best pressure drop
performance available in any check valves
on the market. Compact design wafer type check
valves are for silent operations in essential.
Wafer check valves are suitable to install
