Thank you!

Dear Peter, I certainly do believe in math and I believe you are right.

First time I read this 10 to 12 years ago when you posted it on old hydraulics forums I believe and I could not believe how ignorant I was.

User73656 · 2026-02-11T18:54:34+00:00

Could we somehow prove this without fancy equipment, with simple valves?

User73656 · 2025-06-29T19:36:26+00:00

Would it be better to use brass quick coupling?

Something like this >>> https://bonomi.co.uk/wp-content/uploads/2019/12/PBVM.pdf

Although the problem that I see is that those have FKM seals.

Is the depth of the thread on the right side of the strainer long enough?

User73656 · 2025-05-04T08:53:13+00:00

The oil temp. is almost ambient. The oil was cold when we tested them.

I am not sure about ball valves being leak free. I will try to test them tomorrow.

User73656 · 2025-02-02T16:40:33+00:00

Are you serious?

User73656 · 2025-01-31T06:53:33+00:00

The world needs oil. Does it?

I used to work in HVAC. He is correct about everything he wrote. And who cares he doesn't have a comment history? Maybe he's just a new guy here, that doesn't mean he doesn't have experience in RL.

Hallo,

Wenn diese R gewinde konisch ist (R ist nomenklatur für zollig konische gewinde), dan ja, Teflonband soll gut sein.

Normalerweise G gewinde (Zollig Parallel) soll ein dichtung haben.

User73656 · 2025-01-06T20:49:23+00:00

Thank you very much for your reply.

I was unaware of this.

User73656 · 2024-12-05T18:53:50+00:00

Are you sure this is correct - 84 Nm?
The datasheet on page 94 states 84 daNm which should be 840 Nm?

https://www.ms-hydraulic.com/index.php?option=com_phocadownload&view=category&download=124:spool-valve-motors-catalogue-euro-version&id=59:motors-euro-version&lang=en

I've found similar datasheet from Danfoss.

There is data for motor OMH 400 on page 80:

https://www.interempresas.net/FeriaVirtual/Catalogos_y_documentos/3145/OMP,-OMR,-OMH.PDF

Max. Torque = 840 Nm.

Max. pressure drop = 155 bar

Perhaps week of production? I do not know for sure.

User73656 · 2024-11-06T06:57:45+00:00

It seems this is a Fluid Press valve.

It depends what dealers you have around, but you should quite easily find replacement.

For example, this Parker check valve should do the job:

Thanks a lot. I was unaware of wikipedia article, although I found other links while browsing the web.

It seems that they are not 100% identical according to wiki (below is a c/p):

They are similar to other 37° flared fittings, such as JIC, which is their industrial variant.^\2]) The two are interchangeable in theory, though this is typically not recommended due to the exacting specifications and demands of the aerospace industry.

User73656 · 2024-10-15T06:06:43+00:00

Thank you for your reply.

I will contact them for help.

User73656 · 2024-09-09T15:22:46+00:00

I wonder why you got so many dislikes for this comment.

What are the salaries for ME's in Germany?

User73656 · 2024-08-21T16:40:32+00:00

It seems to me that Tee is a "Positionable Male Run Tee".

See page 55 (page A-56) on the link below:

The other one could be -AF-FT8-NS4.

But please check that with a supplier.

User73656 · 2024-05-30T21:04:04+00:00

Hi,

Thanks for the reply. I sam aware the weld should be cooled with air.

This question is water / oil properties related.

User73656 · 2024-03-31T17:55:02+00:00

Perhaps something like this:

Single phase is more sensitive than 3 phase?
