Behlen Valve Operated Joiner

Single motor and pump with valves to operate the press.
Hydraulic valve circuit has three positions:
- Loop position, oil is circulated from reservoir through the pump and back to reservoir
- Close position, oil is directed to the cylinders to close the press
- Open position, oil is pumped out of the cyclinders back to the reservoir
Advantages of the Valve Operated Joiner:
- Electrical demands are reduced
- Inrush current during plug reversing is eliminated
- Amperage peaks are reduced
- Load to the motor starter is reduced
- A soft start can be used for the first few seconds of the cycle
- A standard NEMA or IEC motors are used
- Smaller breakers and line wires can be utilized
- The press can be jogged without adding stress to the motor
- A timer shuts the motor off a few seconds after the stitich is made, thereby reducing energy use
- A PLC interface is available
