Hydraulic pump check valve (20 mm thread)

The azworkshop.eu shop offers a professional check valve designed for hydraulic power units used in car lifts, tyre changers and other advanced workshop equipment.

Reliability and safety: This valve is responsible for maintaining pressure in the system by preventing the reverse flow of hydraulic oil. It is an absolutely crucial safety feature that prevents the lifting arms from dropping uncontrollably under load.

Exact product dimensions:

Overall height: 37 mm
Mounting thread diameter: 20 mm
Shank diameter (parts with holes): 13 mm
Hexagon socket size: 24 mm

Installation location and system specification

As shown in the attached diagram of the hydraulic power unit (item no. 2), this component is screwed directly into the main manifold block (the so-called ‘cube’). The valve operates in line with the system’s gear pump, protecting it against unexpected back pressure from the actuators.

The valve is precision-machined from high-grade steel and is supplied complete with seals (O-rings), ensuring a fully leak-proof and quick installation. When you buy from azworkshop.eu, you can be sure you’re choosing tried-and-tested parts that will restore your machines to full working order.

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.
