| DEFINITION OF TERMS |
Tool: | The hydraulic attachment that the auxiliary circuit is intended to power. These |
| may include hydraulic breakers, compactors, shears, etc. |
Operating Pressure: | That pressure at which the tool will naturally operate without influence of out- |
| side pressure relief mechanisms. This pressure is an operating characteristic |
| of the tool and cannot be altered by the end user without changing the tool |
| design. |
Relief Pressure: | The relief pressure is that pressure at which the circuit will dump fluid in order |
| to protect itself from damage. |
Back Pressure: | The pressure at the tool’s connection to the return circuit of the carrier. |
Flow Meter: | Instrument for testing the operating characteristics of a hydraulic circuit. The |
| data usually available from this device are pressure (psi/bar), flow (gpm/lpm) |
| and temperature (°F/°C). |
Restrictor Valve: | A valve on the flow meter which allows the user to simulate an operating tool |
| by adding a pressure load (through restriction) to the circuit. This feature is |
| used to evaluate relief settings and flow ratings at pressure. |
V60/V65/V100 Valves: | A priority flow control valve manufactured by Stanley Hydraulic Tools. Allows |
| for optimum operation of any attachment by providing the proper amount of |
| flow for operation of the tool the “priority” aspect allows the attachment to func- |
| tion properly if another control function is activated. |
Inlet Flow: | The hydraulic oil supplied to the IN port of the tool or valve. |
Regulated Flow: | The flow of oil supplied to the tool by the V60/V100 valve. |
| The oil flow that is supplied by the carriers pump, but not used in the opera- |
| tion of the attachment. |
| regulated flow. |
Pressure Line: | The hydraulic line(s) that supply pressurized oil from the pump to the valve or |
| tool. |
Return Line: | The hydraulic line that connects the OUT port of the tool to the tank circuit of |
| the carrier. |
Cracking Pressure: | The pressure at which the relief valve starts to open. Can be seen by a drop in |
| the flow rate as shown by the flow meter. |
Full Open Pressure: | The pressure at which the relief valve is completely open dumping all system |
| flow to the tank. |
Ambient Air Temperature: | The temperature of the outside air. |
Stabilized Temperature: | The temperature at which the carrier hydraulic system temperature will stop |
| rising during testing or operation. |
