Non-Adjustable 3200 PSI Hydraulic Pressure Relief Valve – SAE 8 ORB
Maximum Pressure Protection for Dump Trailers & Hydraulic Power Units
The Primary Mover 3200 PSI Non-Adjustable Pressure Relief Valve is designed to protect your hydraulic system by allowing pressure to safely build up to 3200 PSI before automatically diverting excess fluid back to the tank.
This is the standard pressure setting for most dump trailers, scissor hoists, and hydraulic power units, providing the full lifting force needed for demanding applications while protecting your system from overpressure.
How It Works
This non-adjustable relief valve is factory preset to 3200 PSI. When your hydraulic system reaches this pressure:
- The valve opens automatically
- Excess hydraulic fluid is redirected back to the reservoir
- Your system is protected from overpressure conditions
This ensures consistent performance with no need for adjustment.
Key Features
- 3200 PSI Fixed Setting: Standard pressure for dump trailer applications
- Maximum Lifting Capability: Allows your system to reach full working pressure
- System Protection: Prevents damage to cylinders, hoses, and pumps
- SAE 8 ORB Ports: Industry-standard connection for easy installation
- Non-Adjustable Design: Reliable, set-and-forget operation
- Direct Replacement: Ideal for restoring or maintaining proper system pressure
Why 3200 PSI Matters
Most dump trailers and hydraulic hoists are designed to operate near 3000–3200 PSI. This pressure level is what allows your system to:
- Lift heavier loads efficiently
- Maintain proper dump angles
- Deliver consistent performance under load
Using a lower-pressure relief valve can significantly reduce lifting capacity, making 3200 PSI the preferred choice for most applications.
Compatibility
This pressure relief valve is designed to work with:
- Primary Mover hydraulic power units
- 12V hydraulic power units
- Gas-powered hydraulic systems
- Dump trailers and truck dump bed conversions
Note: Compatibility may vary depending on your system. Always verify your power unit specifications and port size before installation.
Important Safety Notice
Before installing a 3200 PSI relief valve, confirm:
- Your system components are rated for at least 3200 PSI
- Your hydraulic circuit is designed for high-pressure operation
- Your hoses, cylinders, and fittings meet required pressure ratings
Installing a relief valve above your system’s rated pressure can void warranties and cause equipment failure.
Recommended Applications
- Dump trailers
- Truck dump bed conversions
- Hydraulic scissor hoists
- 12V hydraulic power units
- Gas-powered hydraulic systems

Frequently Asked Questions
It allows your hydraulic system to build pressure up to 3200 PSI, then diverts excess pressure back to the tank to protect your components.
Yes. Most dump trailers and hydraulic power units are designed to operate near 3200 PSI for maximum lifting performance.
Yes, as long as your system is rated for 3200 PSI and uses SAE 8 ORB ports.
If your current system is limited by a lower-pressure relief valve, upgrading to 3200 PSI can restore your system’s full lifting capability.
No. This is a non-adjustable (fixed) relief valve preset at 3200 PSI.
