Description
The RCV3-10-P is a poppet
type, screw-in cartridge check
valve with stroke limiter.
Functional symbol
Sectional view
Operation
This valve remains closed
until the spring bias is
reached at port 1 at which
time the poppet lifts off the
seat and allows ow from port
1 to port 2. The effective
orice in the free ow
direction is adjustable.
