OPERATING
DESCRIPTION
|
Marotta
check valves incorporate a poppet with internal
flow passages for minimal pressure drop. The
poppet has a large L/D ratio, maximizing poppet
guide and minimizing chatter, resulting in very
smooth operation.
The valve uses soft seats for a bubble-tight
seal. A variety of seat materials are available
to ideally meet the application requirements. |
