Classifications of Directional Control Valves

Classifications of Directional Control Valves

1. 2-Way Valve Control
  • Consists of 2 ports, 1 for inlet, the other functions as an outlet.
  • Used in basic fluid control on and off applications.
2. 3-Way Valve Control
  • Incorporates 3 ports: one is inlet, the second one is Outlet and the third port is exhaust.
  • Implemented in Single-acting cylinders and Fluid diversion systems.
3. 4-Way Control Directional Control Board
  • Possess 4 ports two of which are for actuation, the other two function as pressure and exhaust.
  • Widely accepted and used for double-acting cylinders and hydraulic circles.
4. 5-Way Control Board
  • Contains 5 ports, two of them are for actuation, one is for pressure and two exhaust ports are located on the same side.
  • Used mainly in pneumatic systems and advanced automation.
5. Function And Basic Operation Of DCV
  • Hand-operated levers, foot wedges, and buttons can be attached to operate.
  • In small-scale works that need human control, remains the best option.
6. Pilot Operated Directional Control Valve
  • No, it is not mechanical or electrical so it is not force operated. Instead, hydraulics and fluid pressure remote control it.
  • For heavy-duty hydraulic appliques it is recommended.
