2. DC globe valve; in the DC or Y-shaped globe valve, the flow channel of the valve body and the main channel form an oblique line, so that the degree of damage to the flow state is smaller than that of the conventional globe valve, so the pressure passing through the valve The losses are also correspondingly small.

 

3. Plunger globe valve: This form of globe valve is a variant of conventional globe valve. In this valve, the disc and seat are usually designed based on the plunger principle. The valve disc is polished so that the plunger is connected with the valve stem, and the sealing is realized by two elastic sealing rings sleeved on the plunger. The two elastomeric seals are separated by a collar and compress the seal around the plunger by the load applied to the bonnet by the bonnet nut. The elastomeric seals are replaceable and can be made of a variety of materials, the valve is mainly used for "open" or "close", but special forms of plungers or special collars are also available. Used to regulate flow.
