What are theese hydraulic devices

What are theese hydraulic devices

What are theese hydraulic devices

I wonder if somebody on this forum can tell spot what theese adjustable hydraulic devices are ? (See pic): http://www.flickr.com/photos/14275989@N00/305132319/

The devices are inserted into a hydraulic block and looks like they are adjustable. Some numbers are written next to the devices on the hydraulic block with a permanent marker. Perhaps pressure ? Flow ? Looks like some calibration tags or something. The hydraulic block is fed by a double set of hydraulic gear pumps. It has a servo valve for flow control and theese are mounted under the block.

Could it be relief valves ?

Flow or pressure valves ?

Any hints would be appreciated !

"Could it be relief valves ?"


"Flow or pressure valves ?"


Since these type valves usually have an adjustment as shown in your picture. Also, other valves, such as Pilot Operated Check valves may have what appears to be an adjustment but is actually a manual release control.

Many of these Screw-In Cartridge valves have information stamped on one of the flats on the hex sections. If you can see the manifold check out the Flats.

I checked six manufacturers catalogs on Screw-In Cartridge valves and did not see any with the configuration shown in your picture. Needless to say I may not know about all the companies, especially non US, who make Slip-In Cartridge valves.

OilControl pressure relief valves VS-80.

Hello Lukec! Thanks for spotting what the devices are !


RE: What are theese hydraulic devices

Are there any other way you could scan and put the catalog page on flicker.com or something ?

Alternatively: Do you have a link to the manufacturers site or the name of the manufacturer ?

Research Report - Mass Customization Placing Design in the Customers Hands
Products come in all shapes and sizes, and customers demand solutions tailored to their needs. With mass customization software, these two facts can be reconciled in an automated, customer-facing experience called a product configurator. In this engineering.com research report, we examine the different levels of mass customization with the pyramid of product configurators. Taking a look at real-world case studies, we discover how the highest level of the pyramid can enable true engineering automation, saving time and increasing customer satisfaction. Download Now
Research Report - Test and Simulation Survey
We at engineering.com continually hear how engineers and designers will be doing simulation, such as FEA and CFD, and that they will be doing it early in the design cycle. Is this wishful thinking? We found out what it is really like in industry. Read more now. Download Now
White Paper - Effects of AIA Quick Guide to UL 489 or UL 1077
The function of a circuit breaker is to provide overload (thermal) and short-circuit (magnetic) protection to a circuit and its downstream components. A circuit breaker functions like an airbag in a car, protecting circuit components and people by tripping the circuit to interrupt the current flow if it detects a fault condition in the control system.

White Paper - Guide to Integrate Large-Format Additive
As with any new technology, getting into large-format 3D printing begins with investigation. The first question may be a simple one: what does “large-format” mean? For 3D printers, “large” is a relative term. Many extrusion-based (FFF) 3D printers are referred to as desktop machines, because they fit on table space. Some of these have very respectable build volumes – but when it comes to “large-format,” the machines will need their own dedicated floor space. Large-format 3D printers have significant build volumes and are most often found in professional settings, like manufacturing facilities and R&D centers. Download Now
