6.0 Hydraulic & Pneumatic Control
Fuellox for Service trucks will control a pump via a solenoid.
6.1 Pneumatic Control
Fuellox can switch a simple solenoid to energise pneumatic pumps.
Parts
| Label | Part | Description |
|---|---|---|
| U | Air Source | |
| V | Fuellox Relay | |
| W | 2 port normally closed | Energise to open, spring return |
| Y | Air Powered Pump | Diaphragm Pump |
| X | External Bypass | 2 Position Lockable* Ball Valve |
*Note: Use a lockable ball valve to prevent unauthorised usage
6.2 PTO Control
The PTO Control design facilitates the use of a hydraulic rewind hose reel. In these cases, Fuellox needs to start/stop the pump without affecting the operation of the hose reel.
