2/2 Solenoid Directional Valve
SAE 16-Cartridge – 350 bar
Normally Closed
WS16Z-01
Poppet Type - Pilot Operated
150 l/min
350 bar
In the de-energized mode, the valve
blocks ow from port 2 to 1 and acts as
a check allowing ow from port 1 to 2.
When energized, the valve allows ow
from port 2 to 1. Flow from 1 to 2 is
severely restricted in this mode.
Exposed surfaces zinc-plated and corrosion-proof
All valve parts made of high-strength steel with hardened and ground
components to ensure minimal wear and extended service life
Coil seals protect the solenoid system
Wide variety of coils and connectors available
Excellent switching performance by high power HYDAC solenoid
Low pressure drop due to CFD optimized ow path
Operating pressure: 350 bar
Nominal ow: 150 l/min up to 280 bar
100 l/min up to 350 bar
