Response time: energized: approx. 35 ms

When the solenoid coil is not energized, (at pmax, Qmax, ν = 34 mm²/s) de-energized: approx. 70 ms
the valve is open in both directions. substantially extended response times
possible at other operating conditions
When the solenoid coil is energized, the
valve is closed in both directions. Coil type: Coil…-40-1836
