Solenoid Directional Valve
SAE 12-Cartridge – 350 bar
2/2 Normally Closed (Reverse Flow)
WS12ZR-01
Poppet Type - Pilot Operated
110 l/min
350 bar
In the de-energized mode, the valve
blocks ow from 2 to 1 and acts as a
check allowing the ow from 1 to 2.
When energized, the valve allows ow in
both directions.

Excellent switching performance by high power HYDAC solenoid
All valve parts made of high-strength steel with hardened and ground
components to ensure minimal wear and to extend service life
Rigid design by using one-piece-body minimizes the effect of eccentricity and
maximizes reliability
All surfaces zinc-plated and corrosion-proof
Waterproof design standard
Wide variety of connectors available
Low pressure drop by CFD optimized ow-path
