Non-Adjustable 1500 PSI Hydraulic Pressure Relief Valve – SAE #8 ORB

Protect Low-Pressure Hydraulic Systems with Reliable Pressure Control

The Primary Mover 1500 PSI Non-Adjustable Pressure Relief Valve is designed to protect your hydraulic system by limiting maximum pressure to 1500 PSI. Once that pressure is reached, the valve automatically diverts excess hydraulic fluid back to the tank, preventing damage to your system.

This valve is ideal for lower-pressure hydraulic circuits, specialty applications, and systems that require controlled pressure limits rather than full 3200 PSI output commonly found in dump trailer setups.

How It Works

This valve is factory preset to 1500 PSI and is not adjustable. When your hydraulic system reaches this pressure:

  • The valve opens automatically
  • Hydraulic fluid is redirected back to the reservoir
  • System pressure is safely limited to prevent damage

This ensures consistent protection without the need for manual adjustment.

Key Features

  • 1500 PSI Fixed Setting: Designed for controlled, lower-pressure systems
  • System Protection: Prevents overpressure damage to cylinders, hoses, and pumps
  • SAE #8 ORB Ports: Standard hydraulic connection for easy installation
  • Non-Adjustable Design: Reliable, consistent performance with no tuning required
  • Direct Replacement Option: Swap into compatible systems to reduce operating pressure
  • Compact & Durable: Built for real-world hydraulic applications

Compatibility

This pressure relief valve is commonly used with:

  • Primary Mover hydraulic power units
  • 12V hydraulic power units
  • Gas-powered hydraulic systems
  • Custom hydraulic circuits requiring reduced pressure

Note: While this valve works with Primary Mover units, compatibility with other systems may vary. Always verify your power unit and port specifications before installing.

Important Safety Notice

Before installing a 1500 PSI relief valve, confirm:

  • Your application requires reduced pressure
  • Your system is designed to operate below 1500 PSI
  • Your lift capacity expectations align with lower pressure output

Lowering system pressure will reduce lifting force. If your application requires higher lifting capacity (such as most dump trailers), a 3200 PSI relief valve may be required.

Recommended Applications

  • Low-pressure hydraulic systems
  • Specialty equipment and custom builds
  • Hydraulic circuits requiring reduced force
  • Testing or controlled-pressure setups

Frequently Asked Questions

What does a 1500 PSI relief valve do?

It limits your hydraulic system to a maximum of 1500 PSI by redirecting excess pressure back to the tank, protecting your components from damage.

Will this work on a dump trailer?

Most dump trailers require higher pressure (typically up to 3200 PSI) to lift heavy loads. A 1500 PSI valve will significantly reduce lifting capacity and is generally not recommended unless your system is specifically designed for it.

Can I use this to reduce my system pressure?

Yes. This valve can be installed to lower your system’s maximum pressure, but you must ensure your application still performs correctly at 1500 PSI.

Is this valve adjustable?

No. This is a non-adjustable relief valve preset at 1500 PSI for consistent operation.

Will this fit my power unit?

It is designed for Primary Mover power units and other systems using SAE #8 ORB ports. Always confirm compatibility with your specific setup before installation.
