JTEKT Sandwich Reducing Valve HGD2H-B02-SD-025C-D2(P)

Features

  1. Compact miniaturized design. It can be installed at any position with only the space required for one electromagnetic directional valve.

  2. The reducing valve adopts a balanced piston structure, delivering excellent pressure-flow characteristics.

  3. Two independent pressure adjustment sections that can be adjusted separately.

JTEKT (formerly TOYOOKI) HGD2H-B02-SD-025C-D2(P) is an integrated dual-pressure hydraulic reducing valve. It is specially designed for hydraulic circuits requiring two different secondary reducing pressures. It can replace the traditional combination of one reducing valve + one electromagnetic directional valve, saving installation space significantly.

1. Complete Model Interpretation

HGD2H-B02-SD-025C-D2(P)
  • HGD2H: Series name – Dual-pressure control reducing valve

  • B: Structure type – Balanced piston type (stable pressure-flow characteristics)

  • First digit 0: Pressure specification – Low pressure side: 0.2~3.5 MPa

  • Second digit 2: Pressure specification – High pressure side: 2.5~14 MPa

  • SD: Electrical specification – DIN 43650 plug-type terminal

  • 025C: Size specification – Standard 025 type (common standard model)

  • D2: Coil voltage – DC 24V

  • (P): Control port – Port P


2. Core Technical Specifications

Maximum operating pressure: 14 MPa
Dual adjustable reducing pressure range (high & low pressure):
  • High pressure side (H): 0.2 ~ 3.5 MPa

  • Low pressure side (L): 0.2 ~ 3.5 MPa

Rated flow rate: Approx. 30 ~ 40 L/min (02 size)
Applicable fluid: Mineral oil, phosphate ester hydraulic oil
Ambient & fluid temperature range: -20°C ~ 70°C
Mounting type: Sandwich / Stackable type (directly mounted below directional valves)

3. Main Functions & Characteristics

Independent Dual-pressure Control

Built-in two sets of pressure regulating springs for high pressure and low pressure, capable of independently adjusting two output pressures respectively.
Two pressure outputs can be switched rapidly via energization/de-energization of the solenoid.

Compact & Highly Integrated Structure

Integrates functions of reducing valve and electromagnetic switching valve into one unit.
Occupies only the installation space of one electromagnetic directional valve, simplifies hydraulic circuits and reduces leakage points.

Stable Pressure Performance

Balanced piston structure ensures minimal pressure fluctuation under flow rate variation.
Suitable for positioning, clamping and pressure holding circuits with high requirements for pressure stability.

4. Typical Application Scenarios

  • Machine tool hydraulic systems: High-pressure workpiece clamping → Low-pressure holding switching

  • Injection molding machines / Die casting machines: Mold closing high pressure → Pressure holding low pressure control

  • Hydraulic fixtures: Rapid feed (low pressure) → Powerful clamping (high pressure)

  • Automatic production lines: Actuators requiring two operating pressures


5. Electrical & Port Description

Electrical: Single solenoid, DC 24V (D2)
Main ports:
  • P: Primary pressure inlet

  • A: Secondary reduced pressure outlet

  • T: Drain port (return to tank)

Control ports:
  • X: External pilot control port (optional)

  • L: Low pressure adjustment port

  • H: High pressure adjustment port


6. Model Selection & Replacement Recommendations

Same series alternative models:
  • Voltage variation: D1 (DC12V), A1 (AC100V), A2 (AC200V)

  • Pressure range variation: B01 (0.7~7 MPa)

Functional equivalence:
Can replace the combined circuit consisting of 2 standard reducing valves + 1 2-position 4-way solenoid directional valve.
