The PQ valve sits at the heart of this energy saving blow molding machine. By regulating hydraulic pressure and flow proportionally, it supplies exactly the fluid each movement needs, which trims power loss and heat in the hydraulic circuit during plastic jug production.

Combined with a variable-frequency extrusion motor and a double station shuttle clamping system, the MP70FS keeps jug output steady while cutting the energy cost of every cycle.

• PQ Proportional Valve Core: Electro-hydraulic pressure and flow control supplies only the fluid each motion requires, reducing throttling loss and heat.
• Variable-Frequency Motor: Extrusion speed follows demand, so the screw never runs harder than the cycle needs.
• Low Average Power Draw: Average energy consumption stays near 1.5 kW, easing running costs in continuous jug production.
• Stable Jug Moulding: 150 kN clamping force and a large platen keep jug moulds locked and walls even.
• Clean Neck and Flash Control: Down-blowing calibration and a hydraulic clamping lock give a neat neck and a flash-free parting line.
• Double Station Output: Two parallel stations raise jug output under one 70 mm extruder.
• Forty Mould Recipes: Stored settings speed up size changeover.

Household and industrial plastic jugs for detergents, bleaches, and liquid chemicals are the main applications, since continuous output makes the energy savings especially worthwhile.

The machine also suits food and dairy jugs where stable wall thickness and clean necks matter for filling and sealing.

Q: What does the PQ valve do?
A: It regulates hydraulic pressure and flow proportionally, delivering only the fluid a movement needs, which lowers throttling loss and heat in the hydraulic system.

Q: How much energy is saved?
A: The combination of the PQ valve and variable-frequency motor keeps average energy consumption near 1.5 kW, well below the 70 kW installed power.

Q: Does energy saving change output?
A: No. Melt quality and clamping performance are maintained, so output stays stable while waste is removed.

Q: Which jugs suit this machine?
A: Detergent, bleach, and liquid chemical jugs, as well as food and dairy jugs, fit the 1 to 10 L working range.

Every unit is packed in a standard export package with an optional wooden pallet or wooden case for long-distance sea freight. The machine is CE and ISO9001:2008 certified and is supported by remote commissioning, operator training, wearing-part supply, and responsive after-sales service worldwide.
