What is this device??

What is this device??

What is this device??

Can anyone identify what this device is for on the end of this hydraulic cylinder?  

Thanks in advance

RE: What is this device??

Which one?

If we learn from our mistakes I'm getting a great education!

RE: What is this device??

The rectangle metal block and the 6 sided device screwed in by the port.  This is on the rod side.


RE: What is this device??

Strictly a guess, but, probably some sort of pressure control like a Counterblance Valve to retard a vertical rod down cylinder with a load that would try to make it drop when a directonal control was shifted to extend the cylinder.

Some of these Pressure Control valves had an adjustin screw in the end or had the adjustment covered by a Hex Cap.

Looks like it has epoxy on it to prevent adjustment of the setscrew in the end of the body.
An adjustable control of some sort.  Maybe a flow control.


RE: What is this device??

Scrape the paint off the hex faces.  The manufacturer's name and part number may be embossed there.


RE: What is this device??

I hate when that happens, as soon as you give up and ask a question, you solve it.  The cylinder is part of slide mechanism for an RV with a synchronizing cylinder.  In case one of the slide cylinders binds and causes a pressure increase, this device locks the cylinder so damage to the RV can not occur.

Thanks for the help,
Ray D
