Since Seal Globe Valve
Product overview
Since seal globe valve whose closing part (disc) moves along the center line of valve seat. According to the moving form of the disc, the change of the valve seat opening is proportional to the valve stroke. Due to the valve stem opening or closing stroke is relatively short, and has a very reliable cut-off function.
Product Features
1. It is simple in structure and maintenance.
2. The working stroke is small and the opening and closing time is short.
3. Good sealing performance, small friction force between sealing surfaces and long service life.
