up to 75 l/min
up to 350 bar
All 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
Waterproof design standard
Wide variety of connectors available
Rigid design using one-piece body minimizes the effect of eccentricity and
maximizes reliability
Excellent switching performance by high power HYDAC solenoid
Low pressure drop by CFD optimized ow-path
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
from 2 to 1. Flow from 1 to 2 is severely
restricted in this mode.
