The servojet jet tube pilot structure has a better ability to resist oil and solid particles compared to nozzle baffles, resulting in a lower failure rate under harsh conditions.

The built-in LVDT valve core performs full-closed-loop sampling, and the onboard circuit automatically compensates for zero-point offsets due to high and low temperatures, ensuring excellent stability during long-term continuous operation.

The standard D02 is equipped with an O-ring neutral position, and the power-off spring automatically aligns and seals the A/B load oil ports. The cylinder is locked for pressure holding, meeting the safety shutdown requirements of the equipment.

The large flow rate and excellent flow linearity enable a single valve to independently complete high-speed injection, mold locking and pressure holding, pressure increase, and back pressure closed-loop control for all working conditions. Applicable scenarios

Ten-thousand-ton heavy-duty cold chamber die-casting machine high-speed injection unit, ten-thousand-ton large-scale injection molding machine injection sealing closed-loop system, medium-thick plate rolling machine hydraulic AGC pressing, heavy-duty forging hydraulic control system, large-scale hydraulic comprehensive test bench, heavy-load component fatigue testing machine.

Operation and maintenance instructions

Install a 3μm high-pressure precision filter at the front end of the oil inlet main pipe. Replace the first set of filter elements 15 working days after the new machine is put into operation.

Separate the power supply line and the shielded control line for wiring, avoiding power harmonics from interfering with the simulation control signals.

The zero point and gain are calibrated by the original factory, only slight electrical fine-tuning is allowed on site, and it is strictly prohibited to disassemble the pilot component and the main valve core of the jet pipe privately.

When the equipment is left idle and sealed for a long time, seal all P/T/A/B/Y oil ports, dry and store them in a dust-proof warehouse to delay the aging and leakage of the sealing parts.
