The differences between bidirectional solenoid valves and one-way solenoid valves, and the working principle of bidirectional solenoid valves
The difference between a two-way solenoid valve and a one-way solenoid valve
A one-way solenoid valve has an electromagnet at only one end, while a two-way solenoid valve has one at both ends. One-way solenoid valves are mainly two-position without a neutral position, while two-way solenoid valves are three-position with a neutral position. The simple difference can be understood in this way: a unidirectional coil, as the name suggests, is two coils.
The working principle of a bidirectional solenoid valve
Normally closed: The bidirectional solenoid valve is usually in the closed state. When the coil is energized, the solenoid valve opens. After a power failure, the solenoid valve closes. When the solenoid valve is in the open position, the inlet pressure is greater than the outlet pressure! The medium flows from the inlet end to the outlet end.
When the outlet pressure is greater than the inlet pressure, the medium flows from the outlet end to the inlet end. And regardless of whether the medium pressure at the inlet end is greater than that at the outlet end or at the outlet end, the solenoid valve can cut off the medium after power-off.
Features of bidirectional solenoid valves
1. This valve adopts a stainless steel piston seal, completely eliminating the possibility of leakage.
2. Within the operating pressure range, this valve has no distinction between inlet and outlet. That is, it can be used normally when the inlet is used as the outlet and the outlet is used as the inlet.
3. The coil adopts a specially designed high-power coil to ensure the rapid opening and closing of the bidirectional solenoid valve.
4. The interior adopts specially processed 304 stainless steel springs, which can be completely closed when the medium flows from the outlet to the inlet.
5. This valve adopts a direct-acting structure, which can meet the working conditions with very low operating pressure.
