SPCL16-30 Valve
U.S. Patent 7,921,880

SYMBOL:
SPCL16-40 Valve symbol
DESCRIPTION
A solenoid-operated, 3-port, normally-closed, proportional, poppet-type, screw-in
hydraulic cartridge valve for low-leakage blocking and load-holding applications.

OPERATION
When the SPCL16-30 is energized, the poppet lifts to allow flow from port 3 to
ports 1 and 2. Flow at port 2 is typical for load sensing applications and includes
a check valve for isolation.

FEATURES
• Industry-common cavity.
• Continuous-duty rated coils.
• Efficient wet-armature construction.
• Optional waterproof E-Coils rated up to IP69K.
• 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.
