A 3-way directional valve, also called a 3/2 valve, has three ports and two positions. It is used to control the flow of hydraulic oil in a system by starting, stopping, or switching the flow between different functions. The valve can be operated electrically (via solenoid), manually, or through pressure changes. A 3-way directional valve is often used to control a single-acting cylinder or to connect a function to pressure or return, thereby regulating movement within the system.

A 3-way directional valve has three ports and two positions. It is commonly used to control single-acting cylinders or as a pilot control. Depending on the valve’s position, it can either connect a pressure source to a consumer, or connect the consumer to the return line while blocking the pressure port. This makes it particularly useful in systems where a function needs to be controlled with a simple on/off command, but where pressure needs to be relieved when the function is not active.
3-way 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.
If there is a need to operate the directional valve manually – for example during maintenance, troubleshooting, or in emergency situations – the valve can be equipped with a manual override. These are available in two versions: with a maintained position, where the valve stays in the manual position until changed again, or with a spring-return position, where the valve automatically returns to its original state once the manual operation is released.
Hydnet holds the largest stock of Sun Hydraulics cartridge valves in Europe, enabling immediate delivery – in urgent cases, we can often deliver the same day. When you choose Sun Hydraulics, you can be completely confident in your decision. Each cartridge valve is manufactured to the highest quality standards and undergoes thorough testing, with every unit tested individually before it leaves the factory. This ensures outstanding performance and maximum operational reliability.
