Description Nominal width 8 … 50 Component series 1X Maximum operating pressure 16 bar, 10 bar Features Water valves are suitable for cooling circuits of liquid fluids Electromagnetically indirectly operated Diaphragm valve with closing damping Simple, compact design Solenoid can be replaced without any tools Ideal for use as water valve to DIN EN 60730-2.8 Product description Electromagnetically operated 2/2 directional water valves according to this standard are poppet valves with hydraulic positive stop damping, in which a diaphragm blocks the flow. The valves are actuated by a solenoid, the force of which is supported by the differential pressure between the valve inlet and the valve outlet (Δpmin = 0.1 bar).
