Twin solenoid SZ 8A3 xx

Twin valve control solenoids for hydraulic valves – size 2

Zwilling valve control solenoids combine two separately controllable pressure-resistant single-stroke solenoids in a common housing. They are used to actuate valves (mostly pilot valves) and are characterized by their extremely compact design.

The solid housing, which is attached to the valve with three screws, accommodates the flameproof armature tube and allows an operating pressure of 50 bar.

Optionally available with manual override and a wide variety of connection sockets (AMP, Deutsch, DIN, Schlemmer, etc.), it is one of the products with the widest range of variants.

Electrical design: Design and testing according to VDE 0580
Electrical connection: DIN EN 175301-803 form ‘A’.
Protection class IP65 according to DIN VDE 0470EN 60529 in connection with a cable plug according to DIN 43640
