DS3 are spools directional valves that control passage and direction of a flow, for subplate mounting. They are available with 3-ports and 4-ports design, with spring return or mechanical detent. The valve body is made with high strength iron castings provided with wide internal passages in order to minimize the flow pressure drops. 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.

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

DS3 valves range also includes versions for high IP degree and corrosion resistance and a version with UL certified coils.

Solenoid valves are electromechanical valves that are designed to control the passage of a fluid.
Valves are mechanisms that are used to regulate the flow of fluids. They can have multiple functions, such as directing the flow, limiting the pressure, preventing the passage of fluids or varying the speed of the flow.
Hydraulics consists of products that generate a movement and a force under two conditions: that they are fluid and that they are subject to a pressure.
