SV16-20 Poppet, 2-Way, Normally Closed
DESCRIPTION
A solenoid-operated, 2-way, normally closed, poppet-type, screw-in hydraulic car-
tridge valve, designed to function as a load holding or blocking valve in applications
requiring low internal leakage.
OPERATION
When de-energized, the SV16-20 acts as a check valve, allowing fl ow to pass from
➀ to ➁, while blocking fl ow in the reverse direction.
When energized, the poppet lifts to open the
➁ to ➀ fl ow path. In this mode, fl ow
from
➀ to ➁ is severely restricted. If this path is required, see model SV16-22,
page 1.046.1.
Operation of Manual Override Option: To override, push button in, twist counter-
clockwise 180° and release. In this position, the valve will remain open.
To return to normal operation, push button in, twist clockwise 180° and release.
Override will be detented in this position.
FEATURES
• Continuous-duty rated solenoid.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Effi cient wet-armature construction.
• Cartridges are voltage interchangeable.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
• Unitized, molded coil design.
• Industry common cavity.
