Installation Information

•Press-fit installation required

•Maintain a close tolerance press fit, as specified. Too loose a fit could allow the Air Poppet Valve to move out of position, while too tight a press fit could interfere with the movement of the valve.

NOTES:

•Pressure to airline of Air Poppet Valve and machine ejection should be activated at the same time. This allows the valve to relieve negative pressure build-up (vacuum) in the cavity during part ejection.

•The airflow to the poppet valve must be fully relieved to the atmosphere after each cycle to ensure that the poppet valve closes before the next injection cycle. Material injected into a partially open poppet valve could cause damage to the valve and/or the mould. Control valves and limit switches to be supplied by the mouldmaker and/or moulder.

•The Air Poppet Valve should never be used as the sole means of part ejection. Material shrinkage and other factors will not allow it to be used as an alternative to ejector pins or stripper plates.

•Do not position Air Poppet Valve directly under hot drop.

•It is recommended to not work frontal surface of the valve.
