HYSV12-21 (2/2 Solenoid Valve, Normally Open)

A solenoid operated, 2-way, 2-position, normally open, poppet-type cartridge valve.


When de-energized, the valve allows a flow from ② to ①, flow from ① to ② is severely restricted in this mode.

When energized, the valve’s poppet closed on its seat, blocking flow from ② to ①. The cartridge will allow ① to ② flow after overcoming the solenoid force.


Operation of manual override option:

To override, push button in to activate. To return to normal valve function, release button.



Max. operating pressure:

207 bar


See pressure drop vs. flow graph

Internal leakage:

3 Drops/min. max. at 207 bar


(-40℃ to +120℃) with NBR material seals

Coil duty rating:

Continuous from 85% to 115% of nominal voltage


Mineral-based fluids with viscosity of 7.4 to 420 cSt.


HY12-2, see page H.1.5

Body material:

6061-T6 Aluminum alloy rated to 207 bar, steel & ductile iron rated to 350 bar
