JTEKT manual directional valve HD3-42MG-BGA-03A

3、 Key functions and features

1. Manual lever operation: Leveraged handle switching, stable operation, reliable positioning, suitable for fixed workstation manual controlJ-tec fluid power system Corporation.

2. positioning deviceAfter switching, maintain the current position without continuous force, suitable for working conditions that require maintaining the direction of the oil circuit (such as clamping and positioning)J-tec fluid power system Corporation.

3. 03 specification high flow rateCompared to the 02 specification, it has a larger diameter and a rated flow rate of 40 L/min. It is suitable for medium to large hydraulic actuators such as large bore cylinders and hydraulic motorsJ-tec fluid power system Corporation.

4. Plate installation compatibilityConsistent with the installation dimensions of the 03A series solenoid valve, it can be quickly replaced and upgraded, and there is no need to change the installation foundation for later electric drive modificationsJ-tec fluid power system Corporation.

5. High voltage adaptation21 MPa pressure resistance covers most industrial hydraulic systems (machine tools, injection molding machines, hydraulic stations, etc.), meeting the requirements of medium and high pressure working conditionsJ-tec fluid power system Corporation.

4、 Applicable scenarios and media

• typical scenarioMachine tool hydraulic system, injection molding machine, hydraulic power unit, small hydraulic circuit of construction machinery, fixture positioning control.

• Applicable MediumMineral hydraulic oil, water ethylene glycol hydraulic fluid, environmentally friendly hydraulic oil (seal compatibility needs to be confirmed).

• Oil temperature rangeConventional -20 ℃ to+80 ℃ (NBR version of seal).

5、 Comparison of Same Specification Selection (03 Series)

6、 Matching and installation tips

1. Must be equipped with a base plate for installation* * SHD03- * * T1A or SHD03- * * T3A series base plates (depending on the direction of the oil circuit) need to be selected and purchased separatelyJ-tec fluid power system Corporation.

2. Sealing and InterfaceThe installation surface needs to be precision machined to 3.2 μ m Rz, and standard hydraulic interfaces are used for P/T/A/B ports. The sealing form is determined by the base plateJ-tec fluid power system Corporation.

3. Substitution and UpgradeCan be installed interchangeably with the 03A series solenoid valve (such as HD3-3W-BGA-03A), and can be directly replaced if the electric drive needs to be changed laterJ-tec fluid power system Corporation.

1. Complete Model Code Interpretation (Structured)

2. Core Technical Specifications

3. Key Functions & Features

• Lever Manual Operation: Stable lever-type switching with reliable positioning, suitable for fixed-position manual control.

• Position Holding Device: Maintains selected position after switching without continuous force applied, ideal for applications requiring sustained flow direction (clamping, positioning, etc.).

• Size 03 High Flow Capacity: Larger bore than size 02, rated flow up to 40 L/min, compatible with medium-to-large hydraulic actuators (large-bore cylinders, hydraulic motors).

• Interchangeable Subplate Mounting: Identical mounting dimensions to size 03A solenoid valves, enabling quick replacement/upgrade; no modification to mounting base when converting to electric drive later.

• High Pressure Resistance: 21 MPa rating covers most industrial hydraulic systems (machine tools, injection molding machines, hydraulic power units) and meets medium-high pressure working conditions.

5. Size 03 Series Model Selection Comparison

6. Installation & Matching Notes

• Mandatory mounting subplate: SHD03-T1A or SHD03-T3A series subplate (select according to flow circuit layout), sold separately.

• Sealing & ports: Mounting surface finished to 3.2 μm Rz; standard hydraulic ports P/T/A/B, sealing performance determined by subplate.

• Replacement & upgrade: Fully interchangeable with size 03A solenoid valves (e.g. HD3-3W-BGA-03A), direct replacement for electric drive retrofit.
