Hi, Pl see below technical information you can see from Sun hydraulics:-
Counterbalance valves should be set at least 1.3 times the maximum load induced pressure.
These valves have load holding function, pilot to open the valve with a additional function of relief valve. This setting of relief...
Think on, Radial piston motor. High torque & low speed. Study your application carefully & there could be a possibility to mount this motor directly without any gear box.

If you see fluid mechanics chapter, you will notice equation for water hammer. According to this equation, after filling up all values given by you, valve closing time should not be less than 0.85 second to avoid surge pressure of 10.5 bar.

Don't you think say if a customer has multiple HPUs(many pumps) in his factory & in this case rather than installing two flowmeters & two high pressure ball valves on each pump, better to have a one off-line Flow/Pressure/Temp Tester which can be used in all HPUs(many pumps) of the factory...
You are right Bud from all aspects. Only thing to add here is, since these additions will add extra cost so it depend upon customer if he is ready to absorb this additional cost. If it is a small customer OR HPU is to be designed for a machine to be sold in very compititive market, I think these...
Dear Hydromech
Pl never lose your heart. We have to remember that Fluid Power Engineering especially hydraulics is not a comprehensive subject of study in mechanical engineering course in most of the engineering colleges in the world. This makes less awreness among graduates unless they come in...

Dear Friends
Has anybody thought of pressure intensification, in case we use double rod cylinders in series to achieve our synchronization purpose. We can achieve our purpose but at the cost of pressure instensification. This pressure intensification will be the highest in the first cylinder &...
All of you have written very correct answers. Just to stress a point from my side that there should be 45 psi pressure difference between flushing valve downstream relief valve & charge pump relief valve. I mean to say setting of charge pump relief valve should be 45 psi more than flushing valve...
Dear danhelgerson
yes, this high velocity particles when enter into return lines having very less pressure & at the same time sudden low velocity, causes loss of pressure energy, see, you have high pressure & low velocity before orifice, now just at orifice, velocity is very high & pressure is...
yes, u r right. compressed air always cost us. So we should do every effort to reduce air leakages & to use compessed air in optimesed & efficient way so that to save energy cost.

Even if you go by Bernaullis equation, you will find while throtlling, just at throttle point or at orifice point whole pressure drop or pressure energy will convert into kenematic energy means velocity of fluid at that point will be very high as proportion to pressure drop. BUT when this...
