Solenoid actuated directional control valve, direct operated, with mounting surface according to ISO 4401-03 standards.

The valve is supplied with 3- or 4-port design, with 2 or 3 positions with a wide range of spools.

The valve body is made with high strength iron castings provided with wide internal paths in order to minimize the flow pressure drop.

Wet armature solenoids with interchangeable coils are used.

The valve is available with DC or AC solenoids.

DC solenoids can also be fed with AC power supply, by using connectors with a built-in rectifier bridge.

The DC valve is also available in a soft-shifting version.

The DC valve is also available with zinc-nickel coating that ensures a salt spray resistance up to600 hours.

It is available a version with UL certified 24V DC coils for Canada and United States. 

Alternative to the standard manual override there are lever, push, knob, push and twist, boot and mechanical detent devices.

2 solenoids - 3 positions with spring centering

Solenoids:

These are essentially made up of two parts: tube and coil. The tube is threaded into the valve body and includes the armature that moves immersed in oil, without wear. The inner part, in contact with the oil in the return line, ensures heat dissipation. The coil is fastened to the tube by a threaded ring, and can be rotated 360°, to suit the available space.
