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