Whenever possible, it is recommended to remove the air bleed plug
and to connect the port (G 1/8) to tank.
The version with heavier spring is generally recommended.

Description
Flow is allowed to pass from V2 to C2 when pressure at V2
rises above the spring bias pressure and the poppet is
pushed from its seat. The valve is normally closed
(checked) from C2 to V2; when sufficient pilot pressure is
present at Pil the pilot piston acts to push the poppet
from its seat and flow is allowed from C2 to V2. The pilot
piston is vented and the pilot pressure required to push the
poppet from its seat is independent from any back-pressure
at V2 port.
