1. Wear resistance: because the vألف core of hard seal bالكلvألف is spray welded with alloy steel and the sealing ring is overlaid with alloy steel, the hard seal bالكلvألف will not have too much wear when opening and closing.
2. Good sealing performance; as the hard sealing bالكلvألف is sealed by manualgrinding, it can not be used until the vألف 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 bالكلvألف is tightly held together with the vألف core by the spring, the switch is very light when the external force exceeds the preload of the spring.
