How are the three states at the middle position of the three-way five-port solenoid valve set?
Thread Content
1. For the three-position five-way solenoid valve (with power disconnected from both coils), there are three states: medium pressure, sealed in the middle, and vented in the middle. How is this determined? Is there a switch button on the solenoid valve, or must a state be selected at the time of ordering? 2. In the sealed state, with a pneumatic double-acting actuator, is it possible to achieve the position-holding function without the need for additional components (such as air lock valves)?
1. Choose it properly at the time of ordering； 2. Not required
The three states of the middle position of the three-way five-port solenoid valve are predetermined during manufacturing and must be selected at the time of ordering. Pneumatic double-acting actuator, equipped with a center-sealed three-way five-position solenoid valve; in the center-sealed state, the actuator remains in its holding position.
