American standard gate valve features:

1. The fluid resistance small, sealing surface Chong brush and erosion by the medium.

2. Open and close more energy.

The flow direction of medium (3) is not restricted, don't reduce the pressure.

4. Simple form, the structure length is short, make good manufacturability, wide application scope.

5. American standard gate valve sealing surface, easy cause erosion and abrasion between maintenance more difficult.

6. Size large.

7. Open needs certain space, open and close time is long.

8. American standard gate valve structure is relatively complex.
