1. Wear resistance: because the vアルベ core of hard seal bすべてvアルベ is spray welded with alloy steel and the sealing ring is overlaid with alloy steel, the hard seal bすべてvアルベ will not have too much wear when opening and closing.
2. Good sealing performance; as the hard sealing bすべてvアルベ is sealed by m年次grinding, it can not be used until the vアルベ core and sealing ring are completely consistent. So his sealing performance is reliable.
3. Light switch: since the bottom of the seal ring of the hard seal bすべてvアルベ is tightly held together with the vアルベ core by the spring, the switch is very light when the external force exceeds the preload of the spring.
4.長い耐用年数
