In what applications are the three-way five-port solenoid valves used for medium pressure, medium pressure relief, and medium pressure sealing?
Thread Content
In what applications are the three types of five-way solenoid valves – medium pressure, medium relief, and medium seal – used? I’ve read a few articles, but there are some contradictions in the information. Does anyone know the answer? In particular, I’m interested in the difference between medium pressure and medium relief
I’ve really never used the three of them; I’m waiting for an expert to explain it.
Medium pressure, medium release, and medium seal refer to several states of the solenoid valve. What does it have to do with the occasion? For example, the two-position operation of a 2-position solenoid valve – in what situations would you use it?

Whether it’s superficial or not. You can force things that don’t go together to be linked. Valves have two states: open and closed. In what situations are they used respectively?
In our factory, the medium-seal type can be used in electro-hydraulic control valves, while the medium-relief type is suitable for pneumatic valves. We haven’t used the medium-pressure type yet, so I’d like to know the specific differences among these three types, their advantages and disadvantages, as well as the situations in which they are appropriate. If you know the answers, please reply; if not, please don’t act like you know everything
Neutral pressure: When neither coil is powered, the pressures in the front and rear chambers of the cylinder remain at the levels they were at after the last coil lost power; the intake valve is closed, and the exhaust valve is also closed. (If this state persists for an extended period, slight leaks at various connections will gradually disrupt this balance.)
Intermediate pressure: When neither coil is powered, there is no pressure in either the front or rear chambers of the cylinder. The intake valve is closed, and the pressures in the front and rear chambers are released through two exhaust valves controlled by solenoids.
High pressure: When neither coil is powered, the pressures in the front and rear chambers of the cylinder remain at the levels they were at after the last coil lost power, and pressure is continuously applied to make these chamber pressures equal to the pressure at the intake side; the intake valve is open, while the exhaust valve is closed.

I’ve seen all of these. If the middle seal is used on a hydraulic cylinder, it won’t give this kind of effect; instead, it offers very high precision. So it seems that the information provided isn’t comprehensive, and there are contradictions as well
If it is a hydraulic device with very high precision, it might not produce this effect; with a very small gap, the hydraulic oil provides a better sealing effect, and the result will be different
