SV08-20J Valve

SV08-20 Valve symbol


A solenoid-operated, 2-way, normally closed, poppet-type, screw-in hydraulic
cartridge valve, with either “J” or “Y” type manual override standard. This valve is
intended as a blocking or load-holding device for low flow circuits having pull-only
manual override requirements for handles or cable linkage.

When de-energized, the SV08-20J/Y acts as a check valve, allowing flow from 1 to 2,
while blocking flow from 2 to 1. When energized, the valve’s poppet lifts to open the 2 to 1
flow path, while flow from 1 to 2 is severely restricted.
Operation of Manual Override Option: To manually override, pull and hold the knurled knob.
This override is not detented. The pull force required is approximately 24 lb The “J” option includes
a male 10-32 thread for a cable attachment. If a cable is used, the internal valve spring may not
provide enough force to overcome internal cable friction. An external means of returning the cable
must be provided by the user.

• Continuous-duty rated coil.
• Hardened patrs for long life.
• Optional coil voltages and terminations.
• Manual override standard.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity.
• Compact size.
