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?

Where can i find a valve that changes the direction of a cylinder by stopping flow or presure then restoring flow or presure? I need double action on a single action circut at 70 gpm. thanks

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.

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

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.

IT IS REQUIRED TO LOCK A VERTICAL SERVO HDRAULIC LINEAR ACTUATOR HANDLING A DEAD WEIGHT WHENEVER A LOSS OF PRESSURISED OIL SUPPLY TO THE ACUATOR. IT SHOULD INSTANTLY STOP AND GET LOCK AT THE SAME POSITION AT THE TIME OF OIL SUPPLY FAILURE.THE OPERATING PRESSURE IS ABOUT 20 BAR TO 100 BAR.KINDLY SUGGEST THE WORKABLE SOLUTION FOR THIS REQUIREMENTS.

Suction Line Oil Level

/4 Comments/in /by

I borrowed this topic from the H & P Forum but I have seen some discussion about my posts:

If positive displacement pump is running and stopped , pump is mounted on tank and suction length above oil level is 200 mm and there is no leakage in suction line and suction chamber ,whether the oil will remain full in suction line after pump stoppage . Will it fall down ?

What happens if length is 400 mm, 800 mm, etc.
