Commercial Shearing's hydraulic valve test stand
1st Quarter 2013
Hydraulic systems & components
Commercial Shearing has recently commissioned a new hydraulic valve test stand. This will enable the company to offer a valuable service to its customers, helping them to achieve major cost savings in replacement valves. Based in Jet Park, Boksburg, Commercial Shearing is a major supplier of hydraulic equipment and solutions to the mining, earthmoving, agricultural and forestry industries.
With this test stand, Commercial will be able to test fully all functions in its wide range of mobile control valves. These include flow, port and main relief valves with spool leakage, pilot and solenoid functions and set individual spool flows; and port pressure relief valves. Options available include open, closed centre, load sensing, pilot and solenoid operated.
The test stand is equipped with three hydraulic pumps:
* A load sensing piston pump with pressure up to 310 bar at 100 l/min.
* A gear pump with pressure up to 240 bar at 47 l/min.
* A gear pump with pressure up to 220 bar at 9 l/min.
It also has a flow meter capable of measuring up to 250 l/min for setting individual section flows on stackable valves. The valve shown under test is the model VP Pulsar proportional control valve which has a maximum flow of 190 l/min and a working pressure up to 350 bar.
