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 valves 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.
