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.
Features
Hardened, precision ground parts for durability
Compact size for reduced space requirements
Low leakage design
Fully guided poppet for smooth operation
