Operation
The poppet remains on its seat
until the pressure drop across
the orice overcomes the
spring force over the seat area.
Full ow will then take place
from port 1 to 2. Flow from
port 2 to 1 will be restricted by
the orice.
Features
Hardened and ground working
parts extend service life.
Robust design with a 350 bar
(5000 psi) max pressure rating.
Compact simple solution in a
single cartridge.
