Directional valves are two-way valves that makes sure hydraulic fluids only flow in a certain direction. They can direct the flow of the pump to either of two paths of the circuit. The spools in directional valves are two-way,two-position valves. These valves are usually open. There are a few prominent points to think about when considering using a directional valve, these are static power limits, dynamic power limits, resistance to flow, switching time and leakage.
We at AHydraulics offer motion controlled directional valves and selectional controlled directional valves. These valves have different uses and specifications. If you need help deceiding which directional valve is best suited for your situation, feel free to contact us.
