DESCRIPTION

A proportional solenoid-operated, 2-way, poppet-type, normally open, screw-in

hydraulic cartridge valve for low-leakage blocking and load-holding applications

OPERATION

When de-energized, the SP16-21 allows flow from 2 to 1. When the valve is partially

energized, the valve begins to throttle the flow from 2 to 1. When fully energized, the

poppet closes on the seat, blocking flow from 2 to 1. Flow from 1 to 2 will occur when

hydraulic pressure exceeds the solenoid force.

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.

FEATURES

• Industry-common cavity. • Efficient wet-armature construction.

• Continuous-duty rated coils. • Optional waterproof E-Coils rated up to IP69K.

• Manual override option.
