DESCRIPTION
A solenoid-operated, 2-way, normally open, piloted poppet-type, screw-in hydraulic cartridge valve designed for low leakage in load-holding or blocking applications.

OPERATION
When de-energized, the SV16-221 allows flow from 2 to 1, while flow from 1 to 2 is severely restricted. When energized, the valve closes, blocking flow from 2 to 1. In this mode, flow from 1 to 2 will be allowed after overcoming the solenoid force. This requires 3.4 to 10.3 bar (50 to 150 psi).
For bi-directional capability, see model SV16-23, page 1.055.1.
Operation of Manual Override Option: To override, push and hold override button.

FEATURES
Continuous-duty rated coil.
Hardened seat for long life and low leakage.
Optional coil voltages and terminations.
Efficient wet-armature construction.
Cartridges are voltage interchangeable.
Unitized, molded coil design.
Manual override option.
Optional waterproof E-Coils rated up to IP69K.
Industry-common cavity.

RATINGS
Operating Pressure: 207 bar (3000 psi); Under certain conditions,
this valve may be used at higher pressures; consult factory.
Proof Pressure: 345 bar (5000 psi)
Flow: Up to 132 lpm (35 gpm)
Internal Leakage: 0.15 cc/minute (3 drops/minute) max. at 207 bar (3000 psi)
Temperature: -40 to 100 °C (-40 to 212 °F) with standard Buna seals
Coil Duty Rating: Continuous from 85% to 115% of nominal voltage
