General Description
The CV103P Series, Poppet-Type, High Flow, Check
Valves allow free flow in one direction while preventing
flow in the reverse direction. They can be used to
isolate portions of a hydraulic circuit or to provide a
free flow path around a restrictive valve.
Operation
Pressure on the inlet of the check creates a force
against the poppet, pushing it off its seat and permit-
ting free flow. Reverse flow through the check is
blocked by the poppet.
