Description
The EFV1-10
*
-0
**
is a
normally open, unidirection-
al, uncompensated, spool
type, two way, proportional
flow control, screw-in
cartridge valve.
Operation
The valve is controlled by
current supplied to the coil.
At zero current, the valve
is fully open from port 2 to
port 3. At 1500 to 1600 mA
(12V coil) the valve is fully
closed. Port 1 is used for
pressure balancing the spool
and armature and must be
blocked in all cases.
The maximum intended
pressure drop is 300 PSID.
At pressure drops above
300 PSID, almost no
increase in flow is obtained.
The intended flow direction
is from port 2 to port 3.
Operation of the valve with
flow from port 3 to port 2
will produce flow vs current
and flow vs pressure drop
curves that are significantly
different from those
obtained with flow from
port 2 to port 3.
Since the spool and arma-
ture are pressure balanced,
the operating pressure
does not affect the operat-
ing characteristics of the
valve. The operating point
of the valve is determined
only by current, pressure
drop and temperature.

Note
To determine operating
characteristics for the flow
rating selected, at a specific
differential pressure, first
determine maximum flow
from upper curve at the dif-
ferential pressure value.
This will be the “100%

The EFV1-10

**
is a
normally closed, unidirec-
tional, uncompensated,
spool type, two way, pro-
portional flow control,
screw-in cartridge valve.
Operation
The valve is controlled by
current supplied to the coil.
At zero current, the valve is
fully closed from port 3 to
port 2. At 1500 mA (12V
coil) the valve is considered
fully open. This is the maxi-
mum intended current level
for use in applications.
Port 1 is used for pressure
balancing the spool and
armature and must be
blocked in all cases.
The maximum intended
pressure drop is 300 PSID.
At pressure drops above
300 PSID, almost no
increase in flow is obtained.
The intended flow direction
is from port 3 to port 2.
Operation of the valve with
flow from port 2 to port 3
will produce flow vs current
and flow vs pressure drop
curves that are significantly
different from those
obtained with flow from
port 3 to port 2.
Since the spool and arma-
ture are pressure balanced,
the operating pressure does
not affect the operating
characteristics of the valve.
The operating point of the
valve is determined only by
current, pressure drop and
temperature.
