Solenoid Directional Valve
SAE 16-Cartridge - 350 bar
2/2 Normally Open (Reverse Flow)
WS16YR-01
Poppet Type - Pilot Operated
150 l/min
350 bar
In the de-energized mode, the valve
allows ow in both directions.
When energized, the valve blocks ow
from 2 to 1. In this mode the valve will
allow ow from 1 to 2 after the hydraulic
force overcomes the solenoid force of 1
to 3 bar.

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 surfaces zinc-plated and corrosion-proof
Waterproof design standard
Wide variety of coils and connectors available
