SV16-21 Poppet, 2-Way, Normally Open
DESCRIPTION
A solenoid-operated, 2-way, normally open, poppet-type, screw-in hydraulic cartridge
valve, designed to function as a load-holding or blocking valve in applications requir-
ing low internal leakage.
OPERATION
When de-energized, the SV16-21 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
SV16-23, page 1.055.1.
When energized, the
➁ to ➀ fl ow path is closed. In this mode, the valve acts as a
check valve, allowing fl ow to pass from
➀ to ➁ after overcoming the solenoid force
(requires 3.4 to 10.3 bar / 50 to 500 psi).
Operation of Manual Override Option: To override, push and hold override button.
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.
• Unitized, molded coil design.
• Industry common cavity.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
