Solenoid Directional Valve
SAE 08-Cartridge – 350 bar
2/2-Normally Closed (Reverse Flow)
WS08ZR-01J
Poppet Type - Pilot Operated
Spring-Return Manual Override
38 l/min
350 bar
In de-energized mode, the valve blocks
ow from port 2 to 1 and acts as a check
allowing ow from 1 to 2.
When energized, the valve allows ow in
both directions.
Wet armature solenoid
Wide voltage tolerance
All valve parts made of high-strength steel with hardened and ground
components to ensure minimal wear and to extend service life
All exposed surfaces zinc-plated and corrosion-proof
Waterproof design standard
