1. Function:

- Limits the maximum pressure in a hydraulic system

- Protects system components from excessive pressure

2. Operation:

- Allows fluid to bypass back to the reservoir when set pressure is exceeded

- Maintains system pressure below a predetermined safe level

3. Components:

- Inlet port

- Outlet port (usually connected to tank/reservoir)

- Spring-loaded poppet or ball

- Adjusting screw or knob

4. Types:

- Direct-acting relief valve

- Pilot-operated relief valve

5. Applications:

- Machine tools

- Mobile equipment

- Industrial hydraulic systems

- Automotive systems (power steering, brakes)

6. Key specifications:

- Maximum pressure rating

- Flow capacity (gpm or l/min)

- Pressure setting

- Response time

7. Maintenance:

- Regular inspection for leaks or damage

- Periodic pressure setting verification

- Cleaning debris from seat and spool

8. Considerations:

- Proper pressure setting for application

- Compatibility with system fluid

- Mounting orientation

When selecting and using a hydraulic relief valve, it's crucial to ensure proper sizing and correct installation to provide effective protection for your hydraulic system. And if You need to replace the Port Relief Valve of your construction machinery, Feel Free To Send Your Inquiry.
