SPCL10-32 Valve
U.S. Patent 7,921,880

SYMBOL:

SPCL10-32 Valve symbol
DESCRIPTION
A solenoid-operated, 3-port, normally closed, poppet-type, proportional, screw-in
hydraulic cartridge valve with an integral, non-isolated load signal to pilot counterbalance
or other control valves in bridge circuit applications.

OPERATION
When de-energized, the SPCL10-32 blocks flow at all ports. When energized,
proportionally-regulated flow is allowed from 3 to 1 with a load-sense signal supplied
at 2. Reverse flow is not allowed from 1 to 3. When using this valve in bridge circuits,
seals should not be used on the pilot pistons of the pilot-operated check valves. This
is to avoid trapping oil which would keep the pilot-operated check valve open.
Note: If low voltage is expected on the machine, 12 or 24 volt systems will require the
use of 10 volt or 20 volt coils respectively.
See “SP Valves and Coil Operating Parameters,” page 2.002.1_pdf.

FEATURES
• Continuous-duty rated coil.
• Efficient wet-armature construction.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity.
• Reduce manifold space claim.

RECOMMENDED ELECTRONIC CONTROLLERS
The EVDR Series controllers are recommended for use with most HydraForce
proportional valves. These newer electronic controllers are versatile, reliable,
and easily configured and customized for a wide range of applications.
