Parker Proportional Valve D1FP Series Application and Characteristics

Parker Proportional Valve D1FP Series Application and Characteristics

Parker proportional valve application:
1. Universal printing machine
2. Machine tool
3. Blow molding
4. Marine diesel fuel injection/exhaust valve control

Parker proportional valve main features:

1. Actual servo valve dynamic characteristics (± 5% input signal -3 dB/350Hz), suitable for demanding applications, ensuring optimized cycle time
2. Very good repeatability - improved process and product accuracy
3. Robust valve design - minimizes faults
4. Digital electronic products - easily adaptable to applications, flexible to use
5. Short delivery time - no storage required
6. Valve core positioning defined during power outage - optional P-A/B-T or P-B/A-T or center position (overlapping valve core)
7. Provide EtherCAT interface as required - high data speed, short cycle time
8. Optional monitoring and control circuits (D1FP * D, D3FP * D) that can be freely configured

1) Electromagnetic electromagnetic valve refers to a proportional valve that uses a proportional electromagnet as an electrical mechanical conversion component. The proportional electromagnet converts the input current signal into force and displacement mechanical signals for output, thereby controlling parameters such as pressure, flow rate, and direction.

2) Electric type refers to a proportional valve that uses a DC servo motor as an electrical mechanical conversion component. The DC servo motor converts the input electrical signal into rotational speed, and then outputs force and displacement through reduction devices and transformation mechanisms such as screw nuts, gear racks or gear camshafts, further controlling hydraulic parameters.

3) Electro hydraulic refers to a proportional valve with a structure of a torque motor and nozzle baffle as the pilot control stage. Input different electrical signals to the torque motor and output displacement or angular displacement through the baffle connected to it (sometimes the armature of the torque motor is the baffle), change the distance between the baffle and the nozzle, and change the flow resistance of the oil sprayed from the nozzle, thereby controlling the transmission parameters.
