Product Overview
The OD1511213AS000, OD1511213AS800, and OD1531213AS000 are classic models in the Bosch Rexroth OD15 series of 2/2 pilot-operated solenoid cartridge valves (screw-in cartridge valves). Manufactured by Bosch Rexroth Italy EDI/Oil Control, the OD15 series belongs to the VEI platform of 2/2 solenoid poppet-type cartridge valves, widely used in mobile machinery, industrial hydraulic power units, injection molding equipment, and metallurgical hydraulic valve groups.
The OD15 series features pilot-operated poppet-type construction with screw-in cartridge design for direct manifold installation. The valves are characterized by compact structure, fast response, and extremely low internal leakage, with a maximum operating pressure of 350 bar (5000 psi)—making them the mainstream control elements for small-to-medium flow cartridge circuits.

Key Technical Advantages
1. Pilot-Operated Poppet-Type Construction — Extremely Low Internal Leakage
The OD15 series features pilot-operated 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. Normally closed (NC) models provide bidirectional blocking when de-energized, making them 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 150/100 L/min Flow Coverage
The OD15 series delivers 350 bar (5000 psi) maximum operating pressure in a compact cartridge package. Flow coverage ranges from 150 L/min (OD1511213AS000 / AS800) to 100 L/min (OD1531213AS000) , accommodating diverse hydraulic system requirements from small-to-medium to medium-to-large flow applications.
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
The OD15 series adapts UNF (Unified Fine) 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. Wide Temperature Range and Superior Environmental Durability
OD1531213AS000 ambient temperature range covers -30°C to +60°C. OD1511213AS000 and OD1511213AS800 are suitable for diverse industrial and mobile equipment applications, including construction machinery, agricultural machinery, and material handling equipment in demanding operating conditions.

Expert Maintenance Tips
1. Installation Guidelines
OD1511213AS000 and OD1511213AS800 fit 021-E cavity (UNF threaded) . OD1531213AS000 fits UNF threaded cavity. 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.
OD1531213AS000 ambient temperature range: -30°C to +60°C.
Use standard mineral-based or synthetic hydraulic fluids.
3. Electrical Connection Specifications
All models use 24V DC supply.
OD1511213AS800 coil type: S8-356.
Ensure electrical connector is fully locked to maintain effective protection.
4. Seal Material and Fluid Compatibility
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.
