Cylinders in Series

Anonymous said...


Can a single directional control valve operate 2 cylinders if each cylinder uses a breather valve instead of a return line so that one cylinder would push the other closed?

Mono Block Valve

hydo said...
Sorry but i forgot how to post a new question and just jumped in this .
iam having a problem with gear pump witch is connected via a monoblock to a pressure guage.
problem is that when i switch the dcv 'on' the guage showes 190 bar ,but for just for one second
then it start to go doun to 100 bar and stay at 100 bar.

as i switch off and then on again
it goes to 150 and then goes down again.
is it relief walve which is releasing pressure and not settlig down again till pressure goes down to 100 bar , if it is pressure should rise again .can a pilot oprated relief solve this .
forgive me for a so basic and not mind frying question.

Log Splitter Valve

Anonymous said...
I am building a log splitter with a log lift. I have two single spool log splitter valves with detents. Can I use them both in tandem? If so is there anything besides the hose between them needed to do it?

Impulse Test Flow Rate

Valliappan said...
I wanted to do impulse test on a cylinder in fully retracted condtion. Cylinder size Bore 100mm, Rod 60 mm, stroke 1000mm. The annular volume is 5.026 ltrs. The pressure has to be rised from zero to 410 bar in 60 mill sec and brought back to zero (sinosoidal wave). We have to do impulse at the rate of 8Hz. What will be the pump flow reqd to this impulse test assuming the cylinder is initially filled with oil and the pump is reqd to rise the pressure to 410 bar.
