how quick exhaust valves work?

[@wjf213]

That was a very well done video and explained perfectly. Keep up the great work.

+wjf213 Thank you for your visit and nice comment. I appreciate it.

thanks for the information sir, helpful for my channel.

Hello, Mekanizmalar. It seems you have great content, I am after a valve that given a constant water pressure, can quickly exhaust water periodically. Do you have any suggestions? This video seemed to be the closest thing to what I am looking for.

Why there is knocking noise in cylinder while tool is released in CNC VMC?

[@morgan6724]

Hey got an assignment to do here. Can an exhaust valve be used to get air out of the circuit quickly, for example with a pneuamtic door that needs to be opened in an emergency?

[@mekanizmalar]

For opening emergency doors you should use a different circuit. The quick exhaust valve I am talking in here has a different purpose. For example you want the cylinder piston forward at slower speed but return to starting point much faster.

Great graphics for flow and exhaust to ATM.

Thank you for your encouragement.

[@jackp.1711]

well explained. I finally get it.

tnx man u real help me out

[@mekanizmalar]

+gijs volker Thank you for your comment and letting me know that it helped you.

[@gijswh2498]

+mekanizmalar my paint val gun was shooting like 5 meter i block port 2 so ther was no pressure now i shoot like 40m

[@mekanizmalar]

+gijs volker Wow 8 fold increase!

great work

+parag pemgirikar Thank you.

hope like this we won't need a 3 port sov ... 2 port with qev shud suffice ...

[@91Pdowen]

Incorrect, you will still need the 3 port sov to exhaust the pressure at port 1 on the QEV, if you use a 2 port sov you will lock in the pressure and the cylinder wont return. Unless you backed off the upstream self relieving regulator to a pressure whereby the spring can overcome it. But in my honest opinion, stick with a 3/2. Cheers

great

What is difference between pressure relief valve and quick exhaust valve please reply as soon as possible Thank you

[@mekanizmalar]

Pressure relief valve is used in hydraulic circuits. When a piston stalls in mid stroke, pressure rise in the cylinder pipes or hoses, This is not desirable. When pressure is above some preset value, relief valve sends portion of oil to the tank and reduces the pressure to desirable level. However keeping hydraulic pump running in this stalled condition causes hydraulic oil temperature to rise. The quick exhaust valves usually used in pneumatic circuits, to increase response time of a cylinder to pressure change. For exampled, if a piston is pushed forward to do a job and you want to piston to return initial condition as soon as possible. Rather then releasing pressurized air through tubes, than from valve and then silencer, quick exhaust valve immediately releases the air to the atmosphere. However quick exhaust valves usually creates more noise in the system.

[@farcticox1409]

A pressure relief valve opens at a set pressure to protect the circuit/system. Does not have to be hydraulic only, my air compressor has a relief valve to protect the tank if shut of switch fails. en.wikipedia.org/wiki/Relief_valve
