321F35 Parker Lucifer Type Solenoid Valve for PET Bottle Blowing Machine Parts

321F35 solenoid valve is popularly used in bottle blowing machine and blow molding machine, etc. We also produce other solenoid valves in those applications, like 322F35, 421F35, 321H35, 322H35, 321H36, 322H36, 322H75.

Working Principle:

1) In a first phase the N.O. valves (322H35) and N.C. valves (421H35) are energised. The pressure in the circuit is therefore established to a pre-determined level (2 to 15 bar). During the same time the 3/2 valve maintains the mould closed with a 40 bar pressure.

2) In a second phase, the N.C. valve 321H35 is energised and the pressure increases up to 40 bar. Independently from the position of the 421H35 valve, the 321H35 valve assures by design that the 40 bar pressure is maintained and cannot go back into the "low pressure" circuit.

3) In a third phase, the N.O. valve 322H35 is de-energised and permits the discharge of the circuit down to 0 bar.
