working principle:

One in one out: normally closed: when the coil is energized, 2 leads to 1, and 1 and 3 are closed. When the coil is powered off, 2 and 1 are closed, and 1 leads to 3.

One in one out: normally open: When the coil is powered on, 3 and 1 are closed, and 1 leads to 2. When the coil is powered off, 3 leads to 1, and 1 and 2 are closed.

One in two out: When the coil is powered on, 1 leads to 2, and 1 and 3 are closed. When the coil is powered off, 1 and 2 are closed, and 1 leads to 3.

Two in one out: When the coil is powered on, 2 leads to 1, 3 and 1 are closed. When the coil breaks, 2 and 1 close, and 3 leads to 1.

Note:

1. When the pressure at the two inlet ends of the original valve is not equal, a check valve needs to be added.

2. The external dimensions are determined based on the connection method and pressure.
