z Main application is in fast-switching applications e.g. in injection moulding machines
z High ow with low ∆p
z All exposed surfaces zinc-plated and corrosion-proof
z All valve parts made of high-strength steel with hardened and ground components to
ensure minimal wear and extended service life
z Excellent stability throughout ow range
z Excellent dynamic performance
z Coil seals protect the solenoid system
z Low pressure drop due to CFD optimized ow-path

Type of voltage: DC solenoid, AC voltage can be rectied
using a bridge rectier plug, e.g. ZW4
(not supplied)
Current draw at 20 °C: 2.9 A at 12 V DC; 1.45 A at 24 V DC
Voltage tolerance: ± 15% of nominal
Coil duty rating: Continuous up to max. 115%
of nominal voltage at
50° C ambient temperature
Response time: Energized: ≈ 80 ms
De-energized: ≈ 80 ms
Coil type: Coil... –75-3164
The WSM16520V is a direct acting
directional poppet valve – de-energized,
the valve is open in both directions. When
the solenoid is energized, the valve closes
in both directions.
Caution: No orice is to be placed just
before port 1. Only "diffuser orices" may
be used.
Up to 100 l/min
Up to 210 bar
