SPCL16-40 Valve
U.S. Patent 7,921,880

SYMBOL:
SPCL16-40 Valve symbol
DESCRIPTION
A solenoid-operated, 4-port, normally-closed, proportional, poppet-type, screw-in
hydraulic cartridge valve for low-leakage blocking and load-holding applications.

OPERATION
When the SPCL10-40 is energized, the poppet lifts to allow flow from port 4 to ports 1, 2, and 3.
Flow at ports 2 and 3 is typical for load sensing applications and includes a check valve for isolation.

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