If the cylinder is controlled conditions at the time the forward motion diagram as above, the movement of the fluid flow is as follows: Fluid coming from the tank (reservoir) will be pumped through (B), by the first fluid pump all the fluid flows through the steering valve (directional control valve (E) after the fluid pressure exceeds the pressure relieve valve is adjustable on the partly channeled through the relief valve (C) as a result of fluid entry into the tank.
After the fluid can go through the directional control valve (E) and the condition of directional control valve as shown above, the fluid flowing again through the pressure / temperature compressated flow control valve (f) to flow into the cylinder (D), and consequently the cylinder moves forward due to all the fluid from the pump to the cylinder then it all makes part of the fluid will flow through the relief valve.
Meter-In Flow Control-Free Conditions
For other circumstances inflow control with schematic drawing free-flow conditions can be explained as follows:
- Once the fluid flow to the Directional Control Valve (E) via the input point p then the fluid will go into the cylinder (D) consequently the cylinder (D) entered into without control.
- While the fluid that is in front of the piston will be pushed out through the pilot valve and into the directional control valve through point A to get to the tank.
- Once the piston reaches the maximum position behind the fluid pressure will increase and open the relief valve so the fluid will flow through the relief valve to the tank.
