Technical parameters (if the range of specified technical parameters is exceeded when using, please consult Huaye Company)
| Model | HY-SP08-20 |
| Installation location | If possible, the valve should be installed below the tank level. This keeps the amount of oil in the armature and thus avoids instability caused by residual air bubbles. If this installation is not possible, installing the valve horizontally will give the best results. |
