1 straight-through type globe valve

2) DC-type cut-off valve: in the DC or Y-shaped cut-off valve, the flow of the valve body and mainstream line into a slash, so that the destruction of the flow state than the conventional valve is smaller, thus through the valve pressure loss is correspondingly small.

3 Angle Stop valve: In the corner cut

American Standard bellows globe valve ZDAJ41W type stainless steel body stop valve, the fluid needs to be changed in one direction so that the pressure drop through the valve is smaller than the normal structure of the valve.

4 Plunger type globe valve: This form of cut-off valve is the normal valve variant. In the valve, the disc and seat are usually designed based on the plunger principle. The disc polishing plunger is connected with the stem, and the seal is achieved by two elastic seals sheathed in a plunger. Two elastic seals are separated by a sets of rings, and the sealing rings around the plunger are pressed by the load exerted by the bonnet nut on the bonnet. Elastic seals can be replaced by a variety of materials, the valve is mainly used for "open" or "off", but with a special form of plunger or specific ring, can also be used to regulate the flow.
