Product description

General information

The 2/2 directional spool valves are direct operated, pressure-compensated screw-in cartridge valves. They control the start, stop and direction of flow and basically consist of housing (1), control spool (2) and a return spring (3).

Function

In the de-energized condition, the control spool (2) is held in the initial position by the return spring (3). The control spool (2) is actuated by wet-pin DC solenoids (4). The symbols are realized by different spools (N and P). The main ports ➀ and ➁ can be loaded continuously with an operating pressure of 350 barand the flow can be directed into both directions (see Symbols).

The manual override (5) allows for the switching of the valve without solenoid energization.

Notice!

The diagram was determined for coil with valve and medium test block size (110 x 70 x 66), without flow in calm air.

Depending on the installation conditions (block size, flow, air circulation, etc.) there may be a better heat dissipation. Thus, the area of application is broadened.

In single cases, there may be more unfavorable conditions leading to limitations of the area of application.

Attention!

The performance limit was determined at minimum current.
