General Description
The CV101P Series, Poppet-Type, 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
