One way direction valve.

Servicable Valve.

Valve Supplied with:                -Three pole plug connector UNI ISO 4400

                                                  (DIN 43650A) - IP65


Mounting position:                    We advise installation of the valve with the coil

                                                  vertical.  Models 8417, 8418, 8419 must be

                                                  mounted in the horizontal position with the coil



Ambient temperature:             80 Degrees C. in DC

                                                (current) for temperatures higher than 40

                                                Degrees C, the performances (M.O.P.D.)

                                                could decrease.


Special Executions                 - Version with water hammer device for slower

                                                  closing time.


                                                - For models8415 and 8416, coil type B20 (30w) is

                                                  available to increase performances (M.O.P.D.) in

                                                  D.C. to 4 BAR pressue.
