According to the channel direction
1) Direct-type globe valve
2 DC-type cut-off valve: In the DC-type or Y-shaped cut-off valve, the valve body flow channel and the mainstream into a diagonal, so that the flow of the state of the damage than the conventional cut-off valve to small, so the pressure loss through the valve is correspondingly small.
3 Angle Stop valve: In the corner section
In the valve, the fluid only needs to be changed in one direction so that the pressure drop through the valve is smaller than the conventional cut-off valve. 4 Plunger type globe valve: This form of cut-off valve is a conventional cut-off valve variant. In this valve, the disc and seat are usually designed based on the plunger principle. The disc-polished plunger is connected with the stem, and the seal is realized by two elastic seals that are set in the plunger. Two elastic seals are separated by a ring, and the seals around the plunger are compacted by the load exerted on the bonnet by the bonnet nut. Flexible seals can be replaced by a variety of materials made, the valve is mainly used for "open" or "off", but with a special form of the plunger or special ring, can also be used to adjust the flow.
