Solenoid Directional Valve
SAE 10-Cartridge – 350 bar
2/2 Normally Open (Reverse Flow)
WS10YR-01
Poppet Type - Pilot Operated
75 l/min
350 bar
In the de-energized mode, the valve
allows ow in both directions.
When energized, the valve blocks ow
from port 2 to 1. In this mode the valve
will allow ow from port 1 to 2 after the
hydraulic force overcomes the solenoid
force of 2.5 to 10 bar.
