Hi, thank you for the reply.
So the highlighted valve has the same pressure as the valve # 1?
My question is : couldn't the system work without it?
In this configuration, the P1 should first overcome the spring of the highlighted valve a then unload through valve 1.
Wouldn't be easier...
Hi,
I have a question regarding the pump unloading valve.
Below is the link to the datasheet:

I cannot understand what is the point of the section (valve) encircled in a picture below.
I believe...
Hi,
Does anybody have any experience regarding cooling water (glycol + water) compatibility with FKM and NBR seals?
I am referring to the O-rings which can be found on hydraulic hose fittings.
I found this compatibility table from Parker...
Hi,
I came across a hydraulic valve with 205 VDC coil recently.
The coil has a connector with rectifier mounted on it. That means that the voltage applied to the coil is 230 VAC.
I am wondering, why not use an AC valve with 230 VAC coils instead of valve with 205 VDC coils?
Hi,
Need some help to identify a flange.
Attached are the photos of the flange.
According to the designations I would say it could be ASME B16.5 flange with groove RTJ.
Any opinion would be appreciated.
Thank you.
Perhaps you could use:
21.89 x 2.62
12.42 x 1.78
Those are the standard o-rings (see page 3 below):
