DGMFN Flow Control Valves
General Description
These valves are adjustable,
non-compensated flow restrictors. An
integral check valve around the
regulating orifice allows free flow in one
direction and metered flow in the other.
Control is available in “A” only, “B” only,
and “A” and “B” ports as an “X” type
(meter–in) or “Y” type (meter-out).
The “P” port is available only in the “X”
type (meter-in) and does not contain a
reverse flow check.
The valve flow setting is adjustable by
means of either a hex key adjusting
screw and locknut, a hand-adjust knob,
or a micrometer knob with keylock.
A normal or fine metering capability
is available. See the pressure
drop curves on page 26 for detailed
performance difference.
