Hydraulic pressure relief valve 16mm (19mm thread)

The hydraulic pressure relief valve with a diameter of 16mm and a thread of 19mm (3/4-16 UNF) is a key safety component for hydraulic systems in vehicle lifts. Its function is to automatically protect the system from over-pressurisation - the valve blocks the flow until 85% of the set pressure is reached and then precisely discharges the excess fluid, protecting expensive components from damage.

Relief valves are essential for the safety and longevity of hydraulic systems - effectively preventing breakdowns and service downtime.

Frequently Asked Questions

What cables do I need for my two-post lift?

Check the rope termination. If there are any markings on it, the total rope length is very often indicated as well, e.g., L8920. This means the rope length is 8.92 m.

Additionally, to correctly select the rope, you need to provide the following technical parameters:

Rope diameter – measured in the middle section (e.g., 8 mm, 9 mm or 10 mm)
Thread – diameter (e.g., M16)
Thread – length – length of the threaded section (e.g., 14 cm)

The drawing below shows the parameters that must be provided when ordering the rope:
Ropes parameter

What is my machine's model?

Find the nameplate on the device – it usually contains key information, such as:
- Manufacturer
- Device model
- Year of manufacture
- Serial number
If you cannot find the nameplate and do not have the technical documentation, selecting parts based on the model may be difficult. In this situation, we recommend searching for parts by category, photos, and dimensions, which often allows you to precisely match the correct component.

Can I return or exchange the part if it doesn't fit?

Yes, of course.

If the ordered part doesn’t fit, you can return or exchange it within 30 days of the purchase date.

For the return to be accepted, the part must:

be unused and undamaged,
show no signs of installation,
be sent back in its original or appropriately secured packaging.

We care about your shopping experience, so the return process is quick and hassle-free. If you have any doubts, contact us – we’ll be happy to help you choose the right part or guide you through the return process.
