pressure sealed globe valve, refers to a valve whose closing part (disc) moves along the center line of the valve seat. According to this movement form of the valve disc, the change of the valve seat port is proportional to the valve disc stroke. Because the opening or closing stroke of the valve stem of this kind of valve is relatively short, and it has a very reliable shut-off function.
product advantages:
1. Simple structure, convenient manufacturing and maintenance.
2. The working stroke is small, and the opening and closing time is short.
3. Good sealing performance, small friction between the sealing surfaces, and long life.
Product Disadvantages:
1. The fluid resistance is large, and the force required for opening and closing is large.
2. It is not suitable for media with particles, high viscosity and easy to coke.
3. Poor adjustment performance.
