the electronic expansion valve kit of embedded type. Therefore we recommend the product to

1) Equivalent length means a calculated value of the actual length plus pressure loss caused by piping curve.
For instance, the equivalent in the case of 10 horse power should be 125 meters (The detailed calculation
of equivalent length should be referenced in pages V-43).
