A hydraulic cartridge relief valve protects a circuit by releasing excess pressure before it can damage pumps, actuators, hoses, or seals. Within the HydraForce relief valve range, RV08-20 is a direct-acting valve for lower-flow circuits, while RV10-26A-0-N-30 is a pilot-operated valve for higher-flow pressure control. The correct option depends on valve structure, rated flow, pressure range, and manifold cavity.
How Do the Relief Valves Discussed Here Work?
The HydraForce relief valve families discussed here—RV08-20 and RV10-26—are normally closed from port 1 to port 2. When pressure at port 1 reaches the valve setting, the selected valve opens and directs oil to port 2, limiting further pressure increase. After pressure falls, the valve reseats and closes the relief path.
The valve must be selected for the required relief flow and operating pressure. Jade Crown Hydraulic can supply compatible cartridge relief valve alternatives for applications using RV08-20 or RV10-26-series valves after confirming the cavity, spring range, pressure setting, and operating data. To discuss purchasing a matched replacement, contact our hydraulic cartridge valve team with the complete model code and application requirements.
Which HydraForce Relief Valve Alternative Fits Your Circuit?
Choose an RV08-20-type alternative for a lower-flow VC08-2 circuit where compact size and low internal leakage matter. Choose an RV10-26A-0-N-30-type alternative for a higher-flow VC10-2 circuit that requires fast, smooth response to pressure surges.
Jade Crown Hydraulic can manufacture compatible replacement options for both valve types. These products are not original HydraForce parts, and the two types are not interchangeable. The complete model code and application data must be checked before a replacement is recommended.
RV08-20: Direct-Acting Relief Valve for Lower-Flow Circuits
RV08-20 is a screw-in, direct-acting poppet relief valve designed for lower-flow circuits that require low internal leakage. It blocks flow from port 1 to port 2 until pressure at port 1 overcomes the spring force and lifts the poppet from its seat.
| Core parameter | RV08-20 |
|---|---|
| Structure | Direct-acting poppet |
| Rated flow | 22.7 L/min (6 gpm) |
| Pressure rating | 275.8 bar (4,000 psi) |
| Cavity | VC08-2 |
| Spring ranges | 50–500, 100–1,300, 250–2,300, or 250–3,600 psi |
| Maximum internal leakage | 0.25 mL/min (5 drops/min), to 75% of nominal setting |
HydraForce RV10-26A-0-N-30: Pilot-Operated Relief Valve for Higher Flow
HydraForce RV10-26A-0-N-30 is a screw-in, two-stage pilot-operated spool relief valve. When pressure at port 1 opens the pilot stage, the main spool shifts and opens the relief path to port 2. It is intended for demanding higher-flow circuits requiring fast response and low hysteresis.
| Core parameter | RV10-26A-0-N-30 |
|---|---|
| Structure | Pilot-operated, two-stage spool |
| Rated flow | 113.6 L/min (30 gpm) |
| Pressure rating | 241 bar (3,500 psi) |
| Cavity | VC10-2 |
| Adjustment | A: 1/4-inch hex Allen head |
| Body and seal | 0: cartridge only; N: Buna-N seals |
| Spring range | Code 30: 27.6–206.8 bar (400–3,000 psi) |
What Information Is Needed for a Compatible Replacement Quote?
An accurate replacement quotation requires a small set of confirmed inputs. These details allow the manufacturer to identify the correct cavity, pressure range, seal option, and test requirement before preparing a sample.
| Information to provide | Why it matters |
|---|---|
| Complete existing model code or clear marking photos | Identifies adjustment, body, seal, spring, and setting options |
| Cavity or manifold drawing, if available | Confirms the installation interface |
| Required set pressure and maximum relief flow | Defines the target operating point |
| Hydraulic fluid and operating temperature | Supports seal-material selection |
| Order quantity, delivery target, and required reports | Supports sample planning, pricing, and production scheduling |
To evaluate purchasing our compatible product, send these details to our technical team for a replacement recommendation, sample plan, lead-time estimate, and quotation.
