Reject Valve
– The Reject Valve is attached to the pneumatic assembly and contains five
ports as follows:
o
Air Supply Input Port
– The air supply from the Dump valve is connected to the input.
o
Air Supply Output Port 1
– The air supply is fed to one side of a reject device. For
example when fitted to one side of a double acting air cylinder, the air drives a rod
attached to a nylon blade to push product off a conveyor into a reject bin.
o
Air Supply Output Port 2
- The air supply is fed to the other side of a reject device. For
example when fitted to the other side of a double acting air cylinder, the air drives a rod
attached to a nylon blade back to its start position.
o
Air Supply Dump Output Port 1
– When an emergency stop is activated, the air
pressure captured in one side of the reject device is dumped through this port. A
suppressor is fitted to the port to reduce any noise generated.
o
Air Supply Dump Output Port 2
– When an emergency stop is activated, the air
pressure captured in the other side of the reject device is dumped through this port. A
suppressor is fitted to the port to reduce any noise generated
In addition for fail-safe reasons an air pressure switch is fitted in order to alert the operator that the air
supply is low (below 40psi / 2.8 bar) and to shut down the system; generating a fault condition.
The system will be supplied with the pneumatic system already fitted and connected to the applicable
reject device.
