Key Technical Advantages

1. Poppet-Type Leakage-Free Construction — Extremely Low Internal Leakage

The OD15 series features poppet type spool construction, achieving metal-to-metal sealing against the seat in the closed position. Unlike spool-type valves, the poppet design delivers extremely low internal leakage in the closed state, making it ideal for high-pressure hydraulic systems requiring long-term actuator position holding with minimal leakage.

2. Bosch Rexroth Quality — Global Industrial Standard

The OD15 series is manufactured by Bosch Rexroth Italy EDI/Oil Control. Bosch Rexroth has over 40 years of experience in the compact hydraulic systems (CH) market. Every product adheres to Rexroth‘s stringent quality standards and testing protocols.

3. 350 bar High Pressure with 150 L/min Flow Capacity

The OD15 series delivers 350 bar (5000 psi) maximum operating pressure and 150 L/min (40 GPM) flow capacity in a compact cartridge package, accommodating diverse medium-to-large flow hydraulic system requirements.

4. Wet-Type Solenoid Design for Quiet, Long-Life Operation

Features wet-armature solenoid construction—the movable iron core operates fully submerged in hydraulic oil. The hydraulic oil lubricates moving parts to reduce wear and cushions switching impact and vibration. Coils can be replaced without opening the hydraulic system.

5. UNF International Standard Cavity — High Installation Compatibility

OD1502211AS000 adapts 021-E cavity (UNF Unified Fine threaded) . OD1502211BS000 and OD1504211AS000 also adapt UNF threaded cavities. Fully compatible with globally adopted UNF threaded cartridge valve interfaces for direct replacement of same-series, same-specification products. The compact cartridge design significantly reduces external tubing and fittings, minimizing system leakage risk and installation space requirements.

6. Flexible Configuration — Unidirectional and Bidirectional Options

OD1502211AS000 and OD1502211BS000 are normally open unidirectional —allowing one-way flow with check function when de-energized, closing when energized. OD1504211AS000 is pilot-operated normally open bidirectional —allowing bidirectional flow when de-energized, closing bidirectionally when energized. The versatile configuration options flexibly adapt to different circuit design requirements.

Expert Maintenance Tips

1. Installation Guidelines

• OD1502211AS000 fits 021-E cavity (UNF threaded) . Verify cavity compatibility before installation.

• Thoroughly clean the cavity and valve exterior before installation to prevent foreign particles from entering and causing seal damage or spool sticking.

• Follow Bosch Rexroth/EDI specifications for installation torque to ensure proper valve seating.

• Mounting position is optional—any installation orientation is acceptable based on manifold design requirements.

2. Hydraulic Fluid Cleanliness

• Recommended fluid cleanliness: ISO 4406 20/18/14 or better.

• Use standard mineral-based or synthetic hydraulic fluids.

• Max. operating pressure for steel body: 350 bar; for aluminum body: 210 bar.

3. Electrical Connection Specifications

• All models use 24V DC supply.

• OD1502211AS000 coil type: S8-356.

• Ensure electrical connector is fully locked to maintain effective protection.

4. Seal Material and Fluid Compatibility

• OD15 series offers multiple seal material options for different applications.

• Standard seals for mineral oil systems; specialty seals optional for phosphate ester and other fluids.

5. Periodic Maintenance Inspection

• Inspect the valve body for external oil leakage every 2,000 operating hours or at least annually.

• Check electrical connectors for looseness, oxidation, or moisture ingress.

• If response lag or unstable shifting is observed, first check system fluid cleanliness and poppet seal condition.

• The OD15 series poppet design features extremely low internal leakage—if abnormal leakage increase is observed, inspect the valve seat sealing surface for damage.
