A 2-way solenoid directional valve, also known as a 2/2 valve, has two ports and two positions. It functions as a simple on/off valve that either allows or completely blocks the flow. It is used to control the flow of hydraulic oil in a system by either permitting or stopping the flow. The valve is operated by an electrical signal that activates solenoids, which move a spool inside the valve. A 2-way directional valve is commonly used to start or stop the flow to a single function or component in the system.

As the name suggests, a 2-way solenoid directional valve has two ports and functions as a simple on/off switch for flow in a hydraulic system. It has only two positions: open (flow is allowed) or closed (flow is blocked). This type of valve is used in applications where the flow needs to be either fully started or fully stopped, with no intermediate positions.
2-way solenoid directional valves are available in two designs – poppet and spool. A poppet valve is designed to be completely leak-tight in the closed position, making it particularly suitable for load-holding applications where any leakage must be avoided. A spool valve, on the other hand, always has a certain amount of internal leakage due to its design and is commonly used in systems where minor leakage is acceptable or where fast switching is more important than complete sealing.
There is a wide range of solenoids available for solenoid directional valves, with various contact configurations and voltage levels to choose from. Common contact types include Hirschmann and Deutsch, and the solenoids are available for both 12V and 24V. For specific needs, there are also solenoids for alternating current (AC) with built-in rectifiers, as well as ATEX-certified versions for use in explosive environments where special safety requirements apply.
To control the solenoid valve, we offer simple and user-friendly amplifiers and I/O units. This enables smarter and more automated solutions through electronic feedback of parameters such as flow, pressure, or temperature, providing precise control over hydraulic functions.
