FUNCTION The PRINCE valve model RD-1800 is a direct acting ball/spring type pressure relief. The valve is compact and simple in design. This type relief is fast opening and is well suited for pressure spike protection. The performance curves below indicate the low cracking pressure typical to ball/spring reliefs. Please refer to the model RV relief for a system pressure relief. The valve is available with a standard steel seat, model RD-1800S, or with a hardened seat, model RD-1800H. Both models are externally adjustable. |
SPECIFICATIONS Pressure Rating Maximum Operating Pressure: 2,500 psi Adjustment Range: 1,000 psi to 2,500 psi Flow Rating: 20 GPM Filtration: For general purpose valves, fluid cleanliness should meet the ISO 4406 19/17/14 level Maximum Operating Temperature: 180°F Weight: Approx 2 lbs. |
Item Number | Port Sizes | Max Flow |
RD-1850-H STOCKED ITEM | 1/2" NPTF | 16 GPM |
RD-1875-H STOCKED ITEM | 3/4" NPTF | 20 GPM |
FUNCTION The PRINCE valve model RV is a differential poppet type inline relief. The valve is made up of a relief cartridge and a cast iron valve body. The differential poppet type relief provides smooth quiet performance with a minimum variation between cracking and full flow pressures. This type relief is also less sensitive to system contamination. The model RV is well suited as a system relief up to 30 GPM and 3000 psi. It is available in two pressure ranges and both an externally adjustable and shim adjustable version. |
SPECIFICATIONS Pressure Rating Maximum Operating Pressure: 3,000 psi Adjustment Range: 500 psi to 3,000 psi Flow Rating: 30 GPM Filtration: For general purpose valves, fluid cleanliness should meet the ISO 4406 19/17/14 level Maximum Operating Temperature: 180°F Weight: Approx 3 Ibs. |
Item Number | Valve Type | Relief Setting | Port Size |
RV-1H | Adjustable 1500-3000 PSI | 2000 PSI @ 10 GPM | #12 SAE |

RV-4H STOCKED ITEM | Adjustable 1500-3000 PSI | 2000 PSI @ 10 GPM | 1/2" NPTF |
FUNCTION The PRINCE valve model DRV is a differential poppet type double relief. This valve uses the same relief cartridge as the model RV. The double relief is used in systems that require cross over relief protection such a reversible hydraulic motor, or systems that require a cushion valve such as double acting cylinders. |
SPECIFICATIONS Pressure Rating Maximum Operating Pressure: 3,000 psi Adjustment Range: 500 psi to 3,000 psi Flow Rating: 30 GPM Filtration: For general purpose valves, fluid cleanliness should meet the ISO 4406 19/17/14 level Maximum Operating Temperature: 180°F Weight: Approx 5.5 Ibs. |
